We may push the threshold longer to save some engines, but the root of the problem is still there: some engines don't reply to the command ping/isready within a reasonable time.
Yes, fully agree. An idea that may help would be to make the threshold depend on the time control. Of course if you play very short games the current 30 + 40 seconds will not matter, as it will never be reached (and that's ok with me), but when playing LTC games some moves can take 10 minutes or more, and in that case, the engine might be silent for quite a while and 30+40 may be too short. So perhaps use 30+40 with up to a certaint time left to move, and past that value, adjust it as a % of the remaining time?
Anyways, it's as you said, if engines behave well and answer instantly to the isready command, none of this matters at all.
There is another thing though, that I want to ask you. Can you include timestamps (down to the milisecond maybe?) in the engine's log file? Cause I saw this:

That is from the start of the same Rubi Vs. Ethereal game. Forget about Ethereal and look only at Rubi, you'll see this:
Code: Select all
RubiChess 2.2 < setoption name Hash value 4096
RubiChess 2.2 < setoption name Ponder value true
RubiChess 2.2 < setoption name SyzygyPath value D:\Tablebases\Syzygy
RubiChess 2.2 < setoption name UCI_Chess960 value true
RubiChess 2.2 < isready
RubiChess 2.2 < ucinewgame
RubiChess 2.2 > info string Found 510 (254 pawn-less / 256 with pawn) tablebases.
RubiChess 2.2 > readyok
Is the ucinewgame really sent before RubiChess says readyok after it has finished initializing the TBs, or is the log file messing with the order of the lines because it all happens very fast?
I am also in the process of installing Picochess on it, so in theory I should be able use all engines created to run on Arm processors in Banksia also if it were ported to Arm. Keep hope alive! 
This is just a thought, not a request yet ...
