fun - at the expense of mathematics ?

this is funny - score estimator

i enter my kap1 score - and i get a good 700+ score.....and i enter my pp1 score, i get a score exactly 100 points lower. basic probabilistic theory says - to generalise, use as huge a sample space as possible. the sample size the score estimator uses is just about 3.

so did you guys try this out ? many of you out there already have their gmat scores, and would might like to try this out.....let me know how it goes.
