The formula
b=100a/c
How the calculator works through it
It substitutes ground-contact duty percentage, foot ground-contact duration into the formula and exposes every numerical step above. The main output is complete stride-cycle duration, accompanied by Reconstructed ground-contact duty percentage.
Read the result correctly
The complete stride-cycle duration is the direct answer to “rearrange the running ground-contact duty factor relationship and solve for complete stride-cycle duration.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
foot ground-contact duration=0.24 and complete stride-cycle duration=0.72 produce ground-contact duty percentage=33.333333333333336.
Where this model stops being reliable
Define initial and terminal contact consistently and control speed, surface, footwear, sensor threshold, asymmetry, and averaging.
Learn it by changing one value
