Not at all. If their bomb sights were useless because of local weather
conditions their accuracy was as good/bad as that of the RAF, as the
USAAF's H2X radar was somewhat imprecise.


Right. When the weather was poor USAAF bombing accuracy was similar to
the RAF, when the weather was good it was significantly better than the
RAF.

From the USAAF Air War Plans Division A-WPD/1

The A-WPD/1 Committee calculated the possibilities
of hitting the plants, in daylight, using the Norden bombsight,
balancing a number of factors to produce an 'accuracy probability". Their
first calculations indicated that to hit a target 100 ft. sq. from 20,000
ft.
would take a mission by 220 bombers, and when all the other elements were
factored in-flak,fighters, weather, whatever-the resources required to
achieve
a 95% chance of destroying such a precision target amounted to either
30 bomb-group missions or a single mission by 1,100 aircraft-which hardly
sounds like precision bombing at all.
