A sedimentation index scales linearly with acceleration through a training factor, so comparing two runs comes down to the ratio of their accelerations. With training factor 5 the first acceleration gives index 60 and a four-times-larger acceleration gives index 240, so the ratio is 4 exactly for the stated toy proportionality ledger; real sedimentation depends on particle size, density contrast, viscosity, rotor geometry, and measurement uncertainty.
A training sedimentation index can scale from checked acceleration. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

A training sedimentation index can use acceleration
With training factor 5, the first acceleration gives index 60.
Sindex=5a=60
The index scales with acceleration
The larger acceleration gives index 240. This is proportionality only, not Stokes settling.
