craps system

i know this is a BJ board, but ive been trying go get some insight on my craps system that i thought out, havent tested in it casino's yet but every time i simulate it it brings back a profit albeit a small one....

here we go....

$10 DONT PASS bet
$5 Pass bet

so on the come out...7,11,12 loses 5 dollars and 2,3 wins 5 dollars

after the come out you lay 5 dollar odds behind the pass line bet, now if the shooter craps out you break even, but if he hits his points your making $1 on 6,8 $3 on 5,9 and $5 on 4,10

like i said its no way to break the casino by any means, and you can up the units to any amount you want to increase your profits

also a very avid blackjack player, just wanted to know what people thought about this crap system
