Sometimes I go crazy and can find myself doing 3-4 RnTs a week. But there are also times where I'll go for long periods without (weeks or even months).

A few things which help:

Good Job (six figure salary)
Additional income streams (passive)
Single (no family commitments)
Cheap rent (parents granny flat)
Overall pretty frugal with money (very casual drinker and restaurant diner) ... albeit I do spend more than the average $ on three hobbies - cycling, golf and collecting luxury watches (I suppose you've got to keep yourself fit and the watch brands I collect do hold or even increase in value aka Rolex).

Would it be fair to say that the average FS punter would average two punts per week (one weekday and one weekend)? That would really add up after a while.
