>>29022080the odds of getting two with identical personality values (what the spot pattern is based on) are astronomical, but some personality value combinations produce the same visible pattern as others despite the values being different. so you could have visually identical spinda without their data/PVs being identical.
it would be amazing if someone somehow figured out which combos produce the same results and used that to find out how many actually visibly different spinda patterns there are, but that would take forever.
