Now maybe I'm wrong, but I have always heard on a 10X odds table it is always better to make a "put bet" on the 4 and 10 than to buy the 4 and the 10. Is this not correct? Looking at the WoO tables a buy bet on the 4,10 carries a HA or 4.76% and a put bet with 10X's odds has a HA of 3.03%. So somewhere I'm making a mistake in my math or am I just not understanding something. Example:

$100 buy bet on the 4,10 would win me $195 ($200 -$5 vig)

$99 put bet($9 flat plus $90 odds) would win me $189($90x2=$180 plus $9 flat)

So basically I have the same amount of money at risk but with a buy bet I win $6? So then how is the HA on the put bet better then the buy bet according to WoO table? I know I must be missing something simple and just not seeing it.

First of all please compare apples to apples. We will make your put bet at $10 plus $90 odds so $100 either way. In Atlantic City you buy the 4 three times and win once according to expectations. You lose twice $105. You win once $200 minus the vig for a total loss of $15. Your put bets lose twice at $100 but wins once at $190 for a total loss of $10.

Then you move to Mississippi. You buy the 4 three times and win once according to expectations. You lose twice $100. You win once $200 minus the vig for a total loss of $5 Your put bet lose twice at $100 but wins once at $190 for a total loss of $10.

Lesson learned: The casinos in Atlantic City are thieving bottom feeders.

Well thanks for the response but you still didnt answer my question LOL on a vig paid only on a win total loss on a buy bet would be $5 and total loss on a put bet would be $10.........................AND THEN MY QUESTION WAS....On the WoO site it say HA on a 4,10 buy bet is 4.76% and HA on a put bet on the 4,10 with 10X's odds is 3.03%......DO YOU SEE MY QUESTION NOW? how can the HA be less on the put bet if you loss more money $10 vs $5?

Thanks for any help

No it doesn't. The WoO site says the HA for a Buy 4 with the vig paid only on a win is 1.67%. Look at the 2nd chart.
