Tom,

I believe OBJ is the geometric mean of ML and A I_Line. That is, the square root of the product of ML and AI_Line.

Then they're going totally off the large rebate they get.

My hunch is that the whales throw in everything, including the kitchen sink, and run a logistic regression model. Their aim is to have (my guess) a 0-2% ROI. But with a 10% rebate, their true ROI is 10-12%. That may not sound like much (my models are way better, but I can't wager 200k per race), but if they play something like 80 races per day at 200k per race, that's a return of $160k PER DAY.

O.K. Thanks. I'll go back and check what might have gone wrong.

Jimmy,

I hope you recover quickly and are back in the saddle soon! (Pun intended)

O.K. Will do in a few weeks (I'm actually going on vacation next week)

Thanks!

In other words, are low values good?

The formulas don't matter. But what direction (increasing or decreasing values) is considered good?

I'll sned you a Zoom invite for a Monday meeting.

What's your e-mail?

Sounds good Jim. What's your e-mail?

I've got scads of ideas and have been conducting scientific research studies for four decades.

I didn't know about your terrible tragedy. So, my condolences and prayers are with you. :pray:

That's easy compared to picking winners in 2yr, old maiden races.
