so im having a disscussion with a freind

[ontheoutside]

about owners take from a purse,,so we used hot rod charlie last week,,,so before i start,,my thinking is probably all wrong,,but im going to throw it out there in hopes of learning some,,and seeing how close i am to being right,,
so
i always thought in stakes the 2nd place finisher gets 20 % so in charlies case last week,,,that 300,000 for owners,,,now i d think they have to pay tax,around id say 40 %,,so that knocks it down to 180,000,,the 10 % to jock and trainer
30,000 each whichs knocks it down to 120,000,,,then i would think 1 % for groom,,hot walker,stall hand,and security,,3,000 each,,so that takes it to 108,000
then theres shipping which my guess is 1,500 round trip,,which brings it to 106,500
so my guess is owners cleared 106,500
am i any wheres close,or way off the beatin path? thanks
