Frequently Asked Questions

What is the empirical Class Par and GLD Speed Figure benchmark at Nakayama Racecourse 1600m?

Nakayama Racecourse (JRA) benchmarks are calibrated directly from GLD Racing's empirical Class Par dataset (865,435 historical starts). At 1600m, 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 1600m?

Nakayama Racecourse features a 310.0m (Turf) / 308.0m (Dirt) homestretch (Right-Handed (Clockwise)). At 1600m, inside draws (Gates 1-4) record a 11.6% SR compared to 5.2% SR for outside draws (Gates 9+), favoring Inside Gates (1–4) & Tactical Speed. Outer-loop mile starting in a chute just 240m before an immediate turn; wide draws suffer severe ground loss.

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.
