Re: 1.g4 opening is losing?

After 1.g4 d5 is around -1, i'd say it's losing.

The Alekhine's 1.e4 Nf6 2.e5 is around +0.7 and probably losing as well.

About SSDF and FIDE : SSDF lowered the rating values for its list several times : https://www.chessprogramming.org/SSDF#Rating_Calibration http://privat.bahnhof.se/wb432434/level.htm This was done because they saw that the ratings for strongest computers is too high compare to human FIDE ratings.
