and there is the
cumulative probability of experiencing a failure on some flight, which
does change (it increases with each flight).

Balogna.

There is no "increasing probability".

If there were, insurance companies would increase your premiums the
more hours you accumulate.

It's ridiculous to assert such a thing.

Actually, they do increase your premiums the more hours you accumulate.
The way it works is... you fly more hours as you fly more years. The
more years you fly, the more =total= premiums you pay, because you pay
for all those years. (They don't refund your money for the first year
just because you didn't have a crash).

Apples to apples. Cumulative to cumulative. Dust to dust.
