Agreed - but as the report notes also:

While inflation accounts for more than one-third of the projected F-35 operating costs, military officials and industry executives were quick to point out that it is nearly impossible to predict inflation over the next half-century.


They also argue that no other weapons program's costs have been calculated over such a long period, and that even shorter-term cost projections for other aircraft do not include the cost of modernization programs and upgrades.

Guess what?  Those costs will be over-budget.
