I would be honest with your history . . . I've been developing with X since Y. If you start to inflate things you're going to fall down a slippery slope where you're not even sure how long you've been doing things and interviews/conversations could get confusing/make you look bad.

Most companies just care that you know your stuff enough to be production so 3-5 years of experience is plenty saying 7 years isn't going to improve your level/pay/experience.

Keep things honest, I wouldn't advertise that you avg. 60 hours per week worked on holidays etc. You'll be better off getting away from that in your next job.

I've done that before and seen people do that for years and when things go bad they are still shown the door like everyone else. So don't be that person. Work reasonable hours for reasonable pay.
