I'm using almost the same implementation of YBWC as Stockfish 6 (without late join), I will try to look at other methods later.
There is an option to use a personality, defined in a .txt file, look at README.txt and personality/default.txt for more details.
I could add more parameters in the next versions.
I didn't use tuning results, Texel's tuning method seems to work with few parameters but other parameters like PST or mobility give bad results.
Happy end of year celebrations.
