The five hour rule was nothing to do with making money and everything to do with insurance requirements.
Hi Blue,
That's certainly what all the schools and clubs say. However I don't believe it.
When I joined the committee of my current club they also had this five year rule. I asked why, and everyone said it was because of an insurance requirement.
When I actually pulled out the insurance policy there was no such requirement and everyone was happy to remove it and replace it with instructors judgement.
I suspect that there is no such insurance requirement even though that's what the schools and clubs say.
