1,2,3,4,5,6,7,8,9,10.

the time from 1 to 10 is 7 seconds. We need to find the ammount of time nessicary for 1 transition to seem smooth.

seconds for smoothness per zoom.

So, to figure out the smoothness time for a set of numbers we must find the difference (call the number 'r')

so

so, 1 to 3.

This is assuming a transition from 1 to 10 in 7 seconds is smooth.
