|As noted before, at any given time the gradient of the 1-2 curve
|(red) is always less than (actually half) that of the 0-2 curve
|(green) - you simply cannot 'drop' one on top of the other!!!

Something -feels- wrong with this sim...
In case 1 the cap charges from 0 to 2v
In case 2 the cap charges from 1 to 2v

In case 1, after a period of time, its output will be 1v
 and, as I see it, will then charge from 1 to 2v
 at this instance in time I start case 2 charging and the two curves
 should be identical, same R, C and instantaneous V

The difference is the time during which case 1 charges from 0 to 1v
 with, initially, twice the current available for the 1 to 2v curve.
