Phases of Worm walking

0.00 second: +0.50 pixel (warmup)

0.02 second: no motion (warmup)

0.04 second: +0.50 pixel

0.06 second: +0.50 pixel

0.08 second: +0.50 pixel

0.10 second: +0.50 pixel

0.12 second: +1.50 pixels

0.14 second: +1.75 pixels

0.16 second: +1.50 pixels

0.18 second: +1.25 pixels

0.20 second: skip here to avoid the slower phase (period = 0.22 second)

0.22 second: +0.25 pixel

0.24 second: no motion

0.26 second: +0.25 pixel

0.28 second: +0.25 pixel

0.30 second: +0.25 pixel

0.32 second: no motion

0.34 second: no motion

0.36 second: no motion

Once the warmup has finished, the walk loops with a 1.00 second period. Each loop, the worm travels exactly 27 pixels. Skipping forces the warmup to repeat each time.
