When you visually compare two hashes, how many digits do you check?

The strings hashed below are "retr0id_18b1f814a8e2d9c4fb9c" and "retr0id_1253dea672ebfa240e94", if you want to check for yourself.
@retr0id Is that 80 bits colliding?
@ryanc yup! I will hopefully have a demo of 96 bits colliding by this time tomorrow, depending on how lucky I get
@retr0id We should talk... this reminds me of an old project I tried to do almost a decade ago.
