H72: course likes draw high

Mechanism and rationale

Drawn in the high third (Flat, 8+ runners) at a course where such runners have beaten the market by 25%+ before. A real draw bias should persist.

The rule

cp_draw_high_runs >= 60 AND cp_draw_high_wins >= 1.25 * cp_draw_high_exp

Reads: cp_draw_high_runs, cp_draw_high_wins, cp_draw_high_exp
