Bias Excess Three-Row Scan - Biophysical Active Matter and Cellular Motion Step by Step

Changing excess forward runs shows bias fraction and net displacement together. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

One excess forward run gives two metres

Forward runs 4 and backward runs 3 leave one excess run. With run length 2 m, net displacement is 2 m.

1\cdot2=2,\quad\frac{1}{7}

Two excess forward runs give four metres

Forward runs rise to 5 while backward runs stay 3. The bias fraction is 1/4 and net displacement is 4 m.

2\cdot2=4,\quad\frac{1}{4}

Three excess forward runs give six metres

With 6 forward and 3 backward runs, bias becomes 1/3 and net displacement reaches 6 m.

3\cdot2=6,\quad\frac{1}{3}
