is 100 possible for SSIMULACRA2 with identical files? #10

there's a port for avisynthplus but I wanted to confirm if it was possible to score 100 with identical files? I've attached some results, and samples I used.

Hi there, yes, we return a score in the range -inf..100.

Could you clarify how to reproduce the problem you're getting? I cannot reproduce it:

Thank you for sharing your results, I wanted to verify if another project (AviSynthPlus-ssimulacra) was not reaching an expected outcome before going forward. Linux, Rust, and Vapoursynth are out of my wheelhouse (various implementations here on github) and I thought it would be easier to ask.
