First thing to ask is whether those values are actually correct...

OK, right.
When I first looked it up I got approx. 60 MMH/FH, which is comparable to F-35/F-22.
I have now seen other sources which state approx. 10-20 MMH/FH, which is comparable to Gripen/Rafale.

Is MMH/FH a subjective quantity, depending on who measures it, or the maintenance crews involved ?

It makes aircrft reliability/availability difficult to ascertain.

Not forgetting the quality of the maintenance work. Spending 20 man-hours to do a 1 man-hour job isn't smart, but nor is not doing it at all because it's only preventative maintenance, not essential.

If you don't schedule time to do your preventative maintenance, your equipment will schedule time for you. And you're not going to like when the equipment decides to do it.

Yeah. Often in cascades, for the sake of the game...

Yes. Lots of UK sourced numbers end up being "fully burdened" to try to account for the entirety of linked activities/costs e.g. security for the base they are operating from, depreciation of assets etc. Whereas others quote a "marginal" number that is very restricted in what it includes by comparison.
