I know what linear means, Bob. If you look at the bottom line of the graph:
----------------------------------------------------------------
5s 20s 1m 3m 10m
you can see that the difference (in time) between equidistant (is this word
correct in english?) points is not constant:
20-5 = 15 sec
60-20 = 40 sec
180-60 = 120 sec
600-180 = 420 sec
So, I see here a logarithmic growing. Am I wrong?
