You would have to refactor the function, I would suggest each file have an adjustment value instead of the absolute tolerance value.

But my recommendation is not to complicate things and to use one tolerance value.
If those buggy files are causing fake positives and need a lower tolerance, I would update/fix those images instead.

What do you think?

I will try setA tonight with tolerance 90 without those 3 files and took the suggested original too. All with tolerance 90. I'll report back. It might skip some dead bases now that I am missing some images...
