Yes, nothing is certain but death and taxes. :)

It is something that, to me at least, deserves further monitoring, as I wrote earlier, especially now that Graham has produced further evidence in that direction. I shall adopt a wait and see approach going forward.

You know, personally I'd rather be wrong about this than not have this discussion at all. I felt it had to be brought up.

Sometimes progress is steps forward with a step backward every now and then...

Not sure why all the hand wringing...

We could allow for that, but if the possibility of a nasty bug is very real, then that would be the opposite of progress.

No regression, but new version for +10 ELO multicore/fast games progress was weird!

If I'm calculating correctly, based on CCRL 40/15 results thus far, likelihood of superiority of SF14.1 over SF14 is below 0.10. That's remarkable, because one would normally expect 14.1 to be not merely stronger, but significantly stronger. While the suspicion is quite warranted, the true reason for this result is far from clear.

As confed said, backward steps are inevitably to happen in a stochastic environment...
If you have found a bug or something suspicious, please hunt it down to the simplest reproducible scenario you can and then report it on github or in a forum if you are unsure.

A regression is suggested by the numbers as well as the engine's behavior. I'm only calling it like I see it.
Of course, it could be a slight and negligible regression in the end, or maybe none at all at faster time controls.
I'm more interested in LTC, anyway, and those are the results I checked.

We are so quick-triggered these days to label things as 'misinformation'. Let's see if the claim is wrong first!
CCRL only requires 200 LTC games to make a rating 'official' and 330 is much more than that, while CEGT has even more games.
There is no regression. SF 14.1 is measureable stronger than SF 14, if the number of played games is high enough:

Exactly, please try my old emulate tool.
90% of coding is debugging, the other 10% is writing bugs.
