Revised math based on Ted's numbers:
QU pool is $5,479,646 after 17.5% takeout
So if Overkill played a $2,600 ticket (or 2,000 straight tickets) and hit it, the return for each $1.30 ticket would be $64.78 resulting in $1.57 less (per ticket) than the posted payout today (which was $66.35) = $129,560 for your hypothetical bet.
The AmWager pools did throw me off a bit doing the back and forth math between ADW's but nevertheless, kudos to others who have helped explain HK racing to Overkill and others wanting to know. I think it's a great product with gigantic sized pools every race day!
