Roanna Carty is the Pred1 pick on the strength of perfect physical metrics: speed 100, bend 100, EP 100 — all field-best by wide margins. The H3 of 105.7 is the highest in the field. She's a Fader who will blaze through the first bend from T5 at extraordinary speed, and the question is whether she can sustain. Her form at Dunstall Park 480m A2 is wildly inconsistent: 82→63→84→42→82, reading 6th, 1st, 4th, 1st, 6th — she either fires or flops with no middle ground. Average performance of 71 is competitive (second-best behind Ballymac Aisling's 74). But the structural position is dire: T5 at 2.9% from 35 runs at Nottingham 500m OR. That's 1 win from 35 attempts — essentially a non-winning trap. Her suitability is catastrophically low: track 0, distance 0, trap 28, class 0 (mean 7.0). She has ZERO Nottingham 500m experience. The speed rank anomaly in the condition data is relevant: speed R1 wins only 8.6% while R2 wins 21.5% — the fastest dog actually loses MORE often at OR 500m Nottingham. This directly undermines the case for picking her on speed alone. Trainer R Short at 28% is strong. This is a pure physical gamble from a near-impossible structural position.
