I tried to edit my other threads post but was unable too, so here is version 2:

I wonder if there is a way to calculate the rate/speed of a dial as it is turned: the dials range is 0-1 , the numbers look a little like this below as the dial is turned clockwise and anti clockwise

0.370435

0.339130

0.302609

0.269565

0.248696

0.264348

0.288987

0.308948

0.340595

speed = distance x time. So I thought perhaps to first calculate the amount between each consecutive number and then multiply that figure by the time between each number (using a timer) to calculate the speed.

i can use a timer and the (*)multiply. But the subtracting is difficult,the numbers move so fast I can’t figure a way to calculate the amount between each number as the list of numbers flies along?

any help would be great : )

peace.
