qwagga1,
I see your point and agree fully with you. It will help if you are able to do some freelance, just to keep current and familiar with "perating in the air". The problem I face and address is that in our case, it's not possible to do any kind of freelance flying because of national legislation. This means we are stucked with some 100-150 hours annual flying period. And that in my opinion it is not enough.
I agree that the annual mimimum flying (hours or missions) will depend on your experience and will also be individaul thing. But again, I'm more interesting thinking, what should the frame (hours and missions) be as a general guideline.
Thanks,
