SASLess, last first, my sqn was a pathfinder sqn and was achieving accuracies in the order of 200-400 yards.
Then regarding your Buff with 51 bombs:
A hit from a 750lb bomb will have less effect that a 1000lb one. It also has the marked disadvantage of 50 misses rather than 20.
Curiously, in the run up to GW1 the USAF sought information about our 90-way bombing system and the intervalometer settings both available and practicable.
