More correctly modeled buffs would help , The altitudes many bomb at are far from realistic. If a Superfort in reality couldn't hit a target from 30,000, then why allow AH3 ones do It. and a real KI67 may have been able to flay at those alts, but certainly could not accurately bomb at that alt.. As for the B17s, The only way they could attain an alt of 32.600 ft was if the weighed 50,000 pounds or less. and again a B17 bombardier could only be certain of hitting the ground with bombs at that alt.
