The line is misleading.

Assuming lowest ambient delta of -1 (just focusing on insulation, no thermal stone or the like):

Naked: 40 seconds

60 insulation: 2 minutes (delta -0.33)

120 insulation: 3 minutes 20 seconds (delta -0.2)

240 insulation: 6 minutes (delta -0.11)

615 insulation: 14 minutes 20 seconds (delta -0.047)

So, the change in delta in relation to insulation is indeed an exponential curve, however, the real time gain is a constant 1 minute 20 seconds for every 60 insulation.
