How strong is Stockfish 10 ?

What's the strength of Stockfish 10 when it is only given 0.1 second thinking time? The answer might surprise you. We played 3 handicap matches SF10 at 0.1 seconds vs known CCRL elo rated opponents at 40/4 level (thus a time handicap factor of 60!) emulating the CCRL 40/4 rating list, table left. We also measured the elo rating when SF10 was given one second vs the 6 second at 40/4 level, table right.
