I am not 100% I get what your asking so I will answer what I think you re asking

The TDC is a mechanical device. Think of it like an abacus. It's keeping track of the data inputted much as an abacus keeps track of the sums entered but also like an abacus it takes a cognitive element to interpolate the data.

I am old enough to remember when calculators hit the scene & they were a marvel of the 60's. You are asking your 40's vintage TDC to do some of the same functions.
