I agree. We are dealing with mathematics as applied to human perception.

Whether or not these steps are perceptible is relatively unimportant,
whereas what matters is that the calculation is effected with the maximum

off, if needed.
Can anyone please either confirm my impression, or rebut?
Thank you.
