Due to the unpredictable starts you get, particularly, it seems, on Endless difficulty, I'm finding that when it's reasonably favourable, it's far too easy. Also, it would seem that the majority will restart if the start is unfavourable (see here) and only 30% never restart.



I'm proposing that the current levels stay, with a new level between Normal and Hard, called "Reasonably Hard" and all levels from Hard upwards be moved down a notch... Endless difficulty will then be left and can be made more difficult.
