Thank you. Any more ideas for intensity or maybe more tweaks? It's already like sport for me - just wanna understand TBM!

High xintensity only work on some pools. Pools that pay for stale shares. (f.ex 2miners.com, miningpoolhub, nanopool, f2pool and many others.)
The Ethereum blockchain reward stale work, and pools that are made for Bitcoin style blockchains doesn't work so good with the TBM miner.
High intensity with tweak might reduce the stales.
You can try 2miners.com with --xintensity 4096, and get 100% accepted shares and few stales poolside, but on flexpool, ethermine, crazypool. ~5% stales and lower payouts.
Thank you. Mining at 2miners
