Same here Steve, was kicking myself for that as well... The .50 P4 payout has been an enigma all meeting. I've seen it contain multiple 20.00+ horses to bring back less than 1K, and days like yesterday where the deepest you needed to go was to include Baffert in the Dmr Futurity ( an easy include 3rd choice in the win pool)
for a mind boggling score.
I've played the whole meeting as my schedule precluded me for following the Spa as much as I would have liked, and I can say I thought the product day in and day out was competitive, fair and exceedingly generous with regard to the value offered ... From a wagering perspective, it reminded me a bit of Tampa, where there were always some gems hidden along the way for those willing to dig.
The .50 P5 with the 16% take out and no consol needs to be modeled at every track in the nation. The average payouts were exponential, and easily the most exciting bet on the menu hands down.
All in all, had a ton of fun with it and plan to follow next year's meet just as closely.
