To modify the question, what is everyone's opinion on the proper bulking to cutting ratio?
I would say 4:1. That is to say if you spend 4 months clean-bulking it should only take you about 1 month to lose the excess fat.
Multiplied out, if you spent 1 year bulking then it should only take you 3 month to lose the fat.
I think at some point this ratio will start to become invalid, for instance if you eat semi-clean and bust-ass in the gym for 3 years I don't think it will take you 9 months to lose the fat which is why people that have the goal of being massive will cut far more rarely.
