its giving incorrect percentile values :( to find percentile rank of score x out of n scores:
(number of scores below x)/n*100 = percentile rank
need to sort the hash first, i used index value of the array to find number of scores below x. x is value of hash taken one by one and returning the percentile

In reply to Re^4: optimize percentile counting in hash by Anonymous Monk
in thread optimize percentile counting in hash by max210
