Elevated Goal — Speed to Goal Simulator

Maximise time-point fraction = speed fraction × goal-altitude factor on final glide to an elevated goal. speed fraction = max(0, 1 − ⁶√((a−b)⁵/√b)); factor = 0.8→1.0 over the e-goal elevation. Valid only if you reach the goal (arrive ≥ 0 m). EN-C polar, climb-then-glide.

Time-point-fraction surface

Red marker = your slider point; gold marker = the optimum (max time-point fraction). Time-point fraction = speed fraction × goal-altitude factor. Speed fraction = max(0, 1 − ⁶√((a−b)⁵/√b)) (a = your task time, b = best task time, in hours). Goal-altitude factor = 0.8 + 0.6·AR − 0.6·AR² + 0.2·AR³ (AR = arrival ÷ e-goal). The flat floor is where you arrive below goal level and miss goal. Polar: sink = 1.05 + 0.00778·(V−37)² m/s (EN-C).
