I'd just like to add that those huds have absolutely no official status, they are "tolerated" as KittYCatS is a free and open market and the team does not intervene in this market except of course in cases of theft and copybotting for example.
Any pricing system is arbitrary and inexact for the reasons Tad gives so i'd say make some honest friends and visit auctions and stores to make your own evaluation. IMO these huds are just another scourge for our market, at best a useless waste of money.
A good example, last year someone was bragging a 9T all top recessives cat , impossible of course as two of the traits had only recently been discovered. A friend who had a pricing hud ran it through for fun and it came out at 5K when obviously it would fetch at least 10 times that in auction and on a bad day.
@Charm - hey girl, you've been in KCs since the beginning and you maybe need to bitch up just a little - for example the next time some fool tries to clobber you with their hud results just tell them to " put it where the monkey puts his nuts " (polite version)
