Thread is open in origins of the engine, along with the evidence, you can read it and get an idea.
Fire 5 is an engine from the Stockfish code, no doubt.
Stop making it out to be much more than it is...
Fire is not 'from Stockfish code, no doubt'.
That can easily be ascertained by using the sim tool, or running the 2 engines side by side.
For any slight similarity there are hundreds of distinct differences, especially concerning eval, move choice, depth, analysis, PV, etc. In addition SF is probably at least 200 ELO stronger.
Concerning the 'Sim' tool, I ran it several times since your post and I regularly get 50% (even better than your 52).
This is quite a good number for any engine, I'm happy with it...I 'm sure there are engines with similar or higher results.
If Fire is more similar now to SF than 2 years ago, this can also be seen as a fairly natural occurrence, as most everyone (IMO) is learning, using, and implementing some or all of it's techniques.
