It is close to 1.5 times, but not quite, it grows slowly.
The best strategy I've been able to come up with grows the exponent roughly every 50s: 47s to get to 100, 51s to 1415, and so on. I wonder if there's a way to do it faster.
At least in the area of 10^15, it takes about N to click on 2x10^i and 4N to click on 1x10^(i+1). Since clicking on 2x10^i approximately halves the time to get to 1x10^(i+1), then it takes N + 4N/2 to get to 1x10^(i+1) if you click on 2x10^i first. 3x10^i is an additional 3N. N + 3N/2 + 4N/3 = 3.8N.
any way to guess how the cost are calculated ?
