Sorry, I don't understand your problem - what on Earth has elevator pitch got to do with anything relating to calibrating your bombsight?!?!
What are you expecting - old-style laser-bombing accuracy? If so you're likely to be disappointed (which isn;t to say that that degree of accuracy is impossible with thr new system, just harder to obtain)
Flying at a set altitude, or close enough thereto isn't hard, and neither is flying at a set speed, so long as you are sensible enough to fly at reduced MPs so that if you need it, you have a little throttle in hand (HT, PLEEEEEAAASSE bring in engine overheating for buffs if they are left on maximum throttle for too long!)
Bombing is a skill, like learning deflection shooting, or indeed JABOing or even dive-bombing (though IMO that latter is the easiest of the lot to acquire). All it needs is some practice. The downside is that by the very nature of things, it takes longer to get lots of practice at level-bombing than just about anything else except torpedo-bombing.
What'd be really nice would be if we were given two different types of bombsight, and in cases where it was appropriate, the ability to choose between types before takeoff. The current system is an odd mix of a vector and a tachometric sight (calibrates like using a tachometric sight to bomb with; and is then used like using a vector sight to bomb with. The old system was like a "magic" vector sight that always accurately predicted where the bombs would actually fall. A proper vector sight would need you to dial in altitude and speed and wind corretion, then you drop when the cross-hairs move over the target. A proper tachometric sight you dial in the same as for a vector sight, but you hold the crosshairs on the target during the run-in, and an automatic system releases the bombs at the right moment. In either case, if you've either dialled in inaccurate info or havent flown your plane according to the data youve dialled in, then your bombs will fall off target by some amount over and above the inherent inaccuracy in the system).
I really can't see as the elevator pitch comes into it anywhere there, m'dear - in what way am I being obtuse? You're not under the misapprehension that you need to be absolutely PRECISELY on the mark in order to bomb acceptably well, are you? The higher the altitude you drop from the less percentage effect a slight variance in speed will have (though it will always have SOME effect), and minor variations in altitude may have no noticable efffect at all.
The only other thing I can think of is if you're trying to pick off targets with individual bombs - if so, forget it. Thats as sillyas trying to get fighter kills by shooting one MG bullet or cannon shell and hoping to get a kill. A very few exceptional aces might be able to manage that trick, or come close to it, but most folks need to send a stream of shells. Similarly, you should be dropping a stick of bombs, not individual ones. Anyone trying to drop single bombs on flak guns using the bombsight has my best wishes, but you're (thankfully) almost certainly doomed to failure (even if only because you arent likely to survive long enough to do much damage that way)
I'd also add that I've always used ramped up settings on all axes aside from roll in just about every flight sim I've flown - because the default flatline settings make planes almost unflyably twitchy in most sims, it seems. But even so - I cant see what on earth fine elevator control has to do with your problems, m'dear... maybe I'm having a particularly noodle-headed day?
