It's a bit early, perhaps, but for those die hard OP fans.

Note how well the Trainer, Jockey, and Owner profiler values do. While I haven't had time to really dig into these values to find good plays (seriously), this is the best I've seen for those particular values.

The DB ranges from 2000. In last year's meet alone (note that prof values at the beginning of the meet used existing prof data _from the prior meet_ to generate the values in this case):

Top Trainer Prof Value:
504 starts, 30.95% wins, +25.46% ROI
Top Owner Prof Val:
717 starts (mucho ties), 20.92% wins, + 10.85 ROI
Top Jockey Prof Val:
504 starts, 32.74% wins, -3.67% ROI
The Top Profiler Value:
504 starts, 30.56% wins, -11.07% ROI
The Top Compilation Value:
504 starts, 28.57% wins, -2.6% ROI
How well does this break down over time, is it consistent, are there other things that can be used to detect the circumstances that will improve on those numbers? Don't know, but that's the fun of SPAT isn't it?
