Solo mining for Gits and Shiggles

I run a full Bitcoin node. Lately I've been playing around with setting up solo mining with BFGMiner, just experimenting with CPUs and GPUs, in full knowledge its a purely academic thing with zero chance of succeeding, intending only to deepen my understanding of the system. Seems to work well, for the most part.
Except when I point my S9's at the pool, I only get about 250 GH instead of 13.5 TH each. I've made sure to turn off overt asciboost when I point them at my experiment, no effect, and they definitely are connected. Does anyone else play around with this stuff and might know the solution already?
FWIW: Ubuntu Bitcoin Core v0.17 BFGMiner v5.5.0
Bitcoin.conf, server, daemon, listen, and txindex set to 1. rpcuser and rpcpassword are set, rpcallowip and rpcport are all good(and proven as I can connect other pcs over the LAN just fine for cpu/gpu)
BFGMiner -o http://127.0.01:8332 -u user - pword --generate-to $address --coinbase-sig "LOL" --stratum-port:3333
Any suggestions?

What is Bitcoin?
Bitcoin is an experimental system of transfer and verification of property based on a network of peer to peer without any central authority.
The initial application and the main innovation of the Bitcoin network is a system of digital currency decentralized unit of account is bitcoin.
Bitcoin works with software and a protocol that allows participants to issue bitcoins and manage transactions in a collective and automatic way. As a free Protocol (open source), it also allows interoperability of software and services that use it. As a currency bitcoin is both a medium of payment and a store of value.
Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed homogeneously by computing the network power, and will be limited to 21 million divisible units up to the eighth decimal place. The functioning of the Exchange is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms, programs making them operational, the data of accounts and discussions of the developers.
The possession of bitcoins is materialized by a sequence of numbers and letters that make up a virtual key allowing the expenditure of bitcoins associated with him on the registry. A person may hold several key compiled in a 'Bitcoin Wallet ', 'Keychain' web, software or hardware which allows access to the network in order to make transactions. Key to check the balance in bitcoins and public keys to receive payments. It contains also (often encrypted way) the private key associated with the public key. These private keys must remain secret, because their owner can spend bitcoins associated with them on the register. All support (keyrings) agrees to maintain the sequence of symbols constituting your keychain: paper, USB, memory stick, etc. With appropriate software, you can manage your assets on your computer or your phone.
Bitcoin on an account, to either a holder of bitcoins in has given you, for example in Exchange for property, either go through an Exchange platform that converts conventional currencies in bitcoins, is earned by participating in the operations of collective control of the currency.
The sources of Bitcoin codes have been released under an open source license MIT which allows to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to insert a copyright notice into all copies.
Bitcoin creator, Satoshi Nakamoto
What is the Mining of bitcoin?
Technical details :
During mining, your computer performs cryptographic hashes (two successive SHA256) on what is called a header block. For each new hash, mining software uses a different random number that called Nuncio. According to the content of the block and the nonce value typically used to express the current target. This number is called the difficulty of mining. The difficulty of mining is calculated by comparing how much it is difficult to generate a block compared to the first created block. This means that a difficulty of 70000 is 70000 times more effort that it took to Satoshi Nakamoto to generate the first block. Where mining was much slower and poorly optimized.
The difficulty changes each 2016 blocks. The network tries to assign the difficulty in such a way that global computing power takes exactly 14 days to generate 2016 blocks. That's why the difficulty increases along with the power of the network.
Material :
In the beginning, mining with a processor (CPU) was the only way to undermine bitcoins. (GPU) graphics cards have possibly replaced the CPU due to their nature, which allowed an increase between 50 x to 100 x in computing power by using less electricity by megahash compared to a CPU.
Although any modern GPU can be used to make the mining, the brand AMD GPU architecture has proved to be far superior to nVidia to undermine bitcoins and the ATI Radeon HD 5870 card was the most economical for a time.
For a more complete list of graphics cards and their performance, see Wiki Bitcoin: comparison of mining equipment
In the same way that transition CPU to GPU, the world of mining has evolved into the use of the Field Programmable Gate Arrays (FPGA) as a mining platform. Although FPGAs did not offer an increase of 50 x to 100 x speed of calculation as the transition from CPU to GPU, they offered a better energy efficiency.
A typical HD/s 600 graphics card consumes about 400w of power, while a typical FPGA device can offer a rate of hash of 826 MH/s to 80w of power consumption, a gain of 5 x more calculations for the same energy power. Since energy efficiency is a key factor in the profitability of mining, it was an important step for the GPU to FPGA migration for many people.
The world of the mining of bitcoin is now migrating to the Application Specific Integrated Circuit (ASIC). An ASIC is a chip designed specifically to accomplish a single task. Unlike FPGAs, an ASIC is unable to be reprogrammed for other tasks. An ASIC designed to undermine bitcoins cannot and will not do anything else than to undermine bitcoins.
The stiffness of an ASIC allows us to offer an increase of 100 x computing power while reducing power consumption compared to all other technologies. For example, a classic device to offer 60 GH/s (1 hashes equals 1000 Megahash. 1GH/s = 1000 Mh/s) while consuming 60w of electricity. Compared to the GPU, it is an increase in computing power of 100 x and a reduction of power consumption by a factor of 7.
Unlike the generations of technologies that have preceded the ASIC, ASIC is the "end of the line" when we talk about important technology change. The CPUs have been replaced by the GPUs, themselves replaced by FPGAs that were replaced by ASICs.
There is nothing that can replace the ASICs now or in the immediate future. There will be technological refinements in ASIC products, and improvements in energy efficiency, but nothing that may match increased from 50 x to 100 x the computing power or a 7 x reduction in power consumption compared with the previous technology.
Which means that the energy efficiency of an ASIC device is the only important factor of all product ASIC, since the estimated lifetime of an ASIC device is superior to the entire history of the mining of bitcoin. It is conceivable that a purchased ASIC device today is still in operation in two years if the unit still offers a profitable enough economic to keep power consumption. The profitability of mining is also determined by the value of bitcoin but in all cases, more a device has a good energy efficiency, it is profitable.
Software :
There are two ways to make mining: by yourself or as part of a team (a pool). If you are mining for yourself, you must install the Bitcoin software and configure it to JSON-RPC (see: run Bitcoin). The other option is to join a pool. There are multiple available pools. With a pool, the profit generated by any block generated by a member of the team is split between all members of the team. The advantage of joining a team is to increase the frequency and stability of earnings (this is called reduce the variance) but gains will be lower. In the end, you will earn the same amount with the two approaches. Undermine solo allows you to receive earnings huge but very infrequent, while miner with a pool can offer you small stable and steady gains.
Once you have your software configured or that you have joined a pool, the next step is to configure the mining software. The software the most populare for ASIC/FPGA/GPU currently is CGminer or a derivative designed specifically for FPGAS and ASICs, BFGMiner.
If you want a quick overview of mining without install any software, try Bitcoin Plus, a Bitcoin minor running in your browser with your CPU. It is not profitable to make serious mining, but it is a good demonstration of the principle of the mining team.

"BFGMiner supports solo mining with any GBT-compatible bitcoin node (such as bitcoind). To use this mode, you need to specify the URL of your bitcoind node using the usual pool options (--url, --userpass, etc), and the --coinbase-addr option to specify the Bitcoin address you wish to receive the block rewards mined." I'm completely new to Bitcoin, so my understanding of mining is still improving. I downloaded BFGMiner, and now I would like to perform some solo mining. (I would rather have it use my GPU, but if a CPU is noticeably easier than I'll go that route first.)
