I'd be interested in seeing at what odds you consider each horse is a lay.

Because on my understanding of racing and wagering, and how I make money, each of your lays has the chance of not being a lay, but a good bet.

Eg you might want to lay one of your horses at $3.00, where it must win 33% of the time to break even, but that same horse might NOT be a lay but a good bet at $5.00 where it only has to win 20% of the time to break even.
