How do I filter out for the high ranking horses...
But, the way the restrictions are set up, you can't eliminate top ranked horses.
Not so. It's actually pretty easy to do.
To filter out rank=1 horses, use the PRD1 avoid Pred Score Rank = 1 filter code.
If you want to filter out both rank=1 and rank=2 horses, use both the PRD1 and PRD2 filter codes... like this: PRD1-PRD2
To filter out the top five ranks use PRD1-PRD2-PRD3-PRD4-PRD5
IOW, the avoid specific rank filter codes combined with the avoid >= rank filter codes allow you to basically pick and choose what ranks you want your UDM to flag by virtue of what you have left over after you are done making eliminations."
