It depends both on how the individual counts cycle length and on how the recovery goes.
Some figure that if they take injections for X weeks, then it's an X week cycle.
Personally I think it better to count cycle length as the entire period that levels are suppressive.
So if wanting to have equal time on and time off, it would matter which way you count time on. I'd suggest the second way.
Also, when counting time off, I think it's fine to include PCT in this time if natural T production comes right back and there never is a difficult period and there were no suppressive factors during the PCT.
But if there are weeks of low T or trying to do a "taper" or using HCG, etc, then those weeks shouldn't be counted towards being "equal time off."
