I find the other secret is not to get TOO high. At 30,000 ft, a 1-2 mph variance equates to a bigger miss than it does at 5,000 ft. I also find that it is easier to calibrate at a somewhat lower altitude (15K is about as high as I ever go). Given the time it takes to get up that high in the first place, I don't find going up to 25-30K very effective strategy if you are trying to keep a base's hangers down.
I love it when I see a bunch of guys going in at 25K+ in buffs, because the simple truth is that most guys at that altitude rarely hit what they are trying to bomb. Somebody always seems to have their calibration off, and most times there is a hanger or two still up after they go through. I get a lot more worried about B17s or B24s coming in at 10-15K, because they can usually get their bombs on target, and they have enough defensive firepower to put up a good fight.
Realize also that if you calibrate at altitude and your speed increases before you drop, you can always chop the thottle for a few seconds to slow down, or in some rides just opening the bomb bay doors will start to slow you down.
