I believe it has something to do with the time in a day. 22:00-01:00 GMT might give you a better chance to catch a GPU, especially a T4.

The benchmark result seems to be unreproducible and may be due to just "jittering". Another benchmark on the same model (not the same CPU though) shows Pass1=768, Pass2=4096, clm=1 as better than...
