Excess Runs Move the Cell - Biophysical Chemotaxis and Gradient Sensing Step by Step

Net displacement comes from excess forward runs times run length. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Only excess forward runs move the mean

There are 2 excess forward runs, and each run length is 12 m.

5 - 3=2

Excess runs times length gives net displacement

The net displacement is 24 m.

2\cdot12=24\ \text{m}
