Time doubling gives 3 elo for Stockfish now

[Jouni]

Look at https://prodeo.actieforum.com/t1895-for ... -in-chains . 1 to 1000 time odds means 10 time doublings. So +2.8 elo for doubling. I was really surprised to result! Stockfish is almost impossible to win from neutral opening with 10 + 0.1 time control . It's over.

But would that also be true if you play 1ms + 0.01ms vs 1 + 0.01?

54% is for 1000:1 time odds, not just 2:1.

Because result was so stunning I ran own test with limited hardware. Engine Stockfish 20260510, book 8moves and handicap 16:1. It ended 53.5-46.5 indicating +24 elo. So +6 elo for one doubling. But You can download Young games and verify (1 core used).
