At fixed spin rate, radius linearly changes the training acceleration. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Two metres at the same rate gives eight acceleration units

Hold spin rate at 2 per second. Radius 2 m gives acceleration 8 metres per second squared.

Three metres gives twelve acceleration units

With the same rate, radius 3 m gives acceleration 12 metres per second squared. The acceleration arrow is checked from the exact product.

Four metres gives sixteen acceleration units

Radius 4 m gives acceleration 16 metres per second squared. This is a training acceleration model, not sedimentation chemistry.
