Bulldog fatigue index

[Centralize]

Can someone please explain how fatigue index is calculated from the fatigue meter reading. Some real numbers would be useful; there are an increasing number of Bulldogs availiable on the market, but no real info on how long they will last for.

What about the Chipmunk? Similar flight profile, considerably older but no mention of fatigue life.

Not an area I ever dealt with on the Bloodknot, but if you get no joy elsewhere drop me an Email and I can probably steer you in the right direction.
