the working window in 4.10 is actually small.................
loaded a B-25 with 500lb bombs (unlimited ammo) and tried to skip (just to see IF the bombs are skipping and donating) with level stabilizer:
20m, skipping yes, exploding no , hence the 2 sec fuze
30m, both ok
40m, ok
50m, ok
60m, not skipping anymore !!!!!!!
thats around 195feet
one have to learn to estimate/calculate the distance to target new, true. in 4.09 you were so low to have the target always in your Revi sight
