System: Top weights for in-form handicap hurdle trainers

Mechanism and rationale

The jumps top-weight system kept to hurdles, where its edge has been steadier.

The rule

race_type = 'Hurdle' AND is_handicap = 1 AND weight_rank_high = 1 AND trainer_kind_runs >= 30 AND trainer_kind_wins * 5 >= trainer_kind_runs

Reads: race_type, is_handicap, weight_rank_high, trainer_kind_runs, trainer_kind_wins
