The time adjustments are basically linear, there's no fancy maths involved. If we took a standard time between two tops that happened to be 46 minutes on a 23hr schedule then for a 21hr schedule the time is simply multiplied by 21/23, i.e 42 minutes. For the majority of timings the maths isn't that simple so the resulting time is rounded to the nearest minute, i.e. 41:30 to 42:29 would all show as 42 minutes. Some people really struggle with moving quickly over rocky ground so the "rockiness" factor takes account of that by increasing the adjusted time by a percentage before the rounding takes place. This is only done on a few sections - Bowfell to Scafell and KirkFell to Green Gable from memory.
Getting the calculations done for the later stages that accurately reflects how people actually move on quick rounds is something that I need to look at. It will need a bit of mathematical jiggery pokery:sneaky:
