nothing to scalp there Doug...
if you wager on Z at 5 dimes and against her with all the other horses parimutual you cant make any money due to large track take out. at 5 dimes and the exchanges she will stay
+260 yes -300 no approx even if she is 7-5 or 3-2 or 8-5 on track..with track ttake out that is more like 2-1 true odds...and she will be slightly overbet on track...so 5 dimes will stay in that +260 -300 range.
