H97: yard in form and fresh

Mechanism and rationale

First run for 150+ days from a yard good with fresh horses AND winning at or above its prices in the last 30 days.

The rule

tx_fresh_runs >= 25 AND tx_fresh_wins >= 1.3 * tx_fresh_exp AND t30_runs >= 10 AND t30_wins >= t30_exp

Reads: tx_fresh_runs, tx_fresh_wins, tx_fresh_exp, t30_runs, t30_wins, t30_exp
