I bothered to check exact values. Actual jump heights in ascending order, rounded to the nearest integer:

Spaz's double jump while standing: 211 pixels
Jazz's uppercut: 226 pixels
Jazz's golden jump: 239 pixels
Spaz's double jump while running: 296 pixels
Spaz's golden double jump: 317 pixels

Data for Spaz is approximate because jump height depends on timing of the second jump; actual maximum values might be slightly higher but certainly not lower.
