Progress through an episode

Each band shows how many episodes of G0.5 were in that band at each second. On a task of one step, an episode is in the band of the furthest stage it reached. On a task of several steps, an episode is in the band its credit has reached, and each band starts at its stage's credit for one step. The dashed line shows the mean Reliability.
