According to one of the patents on OTF , 22 or 23% reflectance. Just about

I'd love to hear some comments about this. Have equipment manufacturers
accounted for this potential error in sensor reflectance?

Common sensor diodes are usually quite small active area ~1mm^2 so unless in
a large cut out the hole/sensor should not be an issue.
