Frequently Asked Questions
What is the empirical Class Par and GLD Speed Figure benchmark at Nakayama Racecourse 2500m?
Nakayama Racecourse (JRA) benchmarks are calibrated directly from GLD Racing's empirical Class Par dataset (865,435 historical starts). At 2500m, standard velocities (m/s) and par finish times are normalized across the JRA class ladder alongside daily track variant and surface moisture adjustments.
What is the barrier draw and running style bias at Nakayama Racecourse 2500m?
Nakayama Racecourse features a 310.0m (Turf) / 308.0m (Dirt) homestretch (Right-Handed (Clockwise)). At 2500m, inside draws (Gates 1-4) record a 10.8% SR compared to 6.3% SR for outside draws (Gates 9+), favoring Inside-to-Mid Stamina Stalkers (Arima Kinen Profile). Arima Kinen (Grand Prix) course: starts on the outer chute, navigates six corners and climbs the 2.2m steep wall three times, strongly favoring inside-to-middle draws.
How do surface going, rail shifts, or sand moisture affect Nakayama Racecourse speed figures?
Rails A/B/C • 310m Short Stretch + 2.2m Steep Wall • Strong Inside/Early Speed Bias. GLD Speed Figures automatically separate true horse velocity from surface speed variants so you can compare Nakayama Racecourse past performances directly against other JRA venues.
