Unfortunately it doesn't work like that or I'd lap F5 for a few hours and claim F8c.
I used to ARC on F6b-6c routes, climbing continuously for between 45mins and and hour. F6b-6c was below my anaerobic threshold so I didn't get pumped - there was no accumulated pump to deal with and the last lap felt no harder than the first.
Your circuit should take about an hour to complete (14 moves x 64 = 896 moves at 4secs per move = 1hr), this is the sort of grade and duration that lots of people regularly ARC on.
I think part of the problem with some people's incredulity about doing this (offer of pints and jet fighters for successful attempts) is that you're stuck within your own narrow frame of reference: you get pumped on it therefore everyone must get pumped on it.
