I've been browsing the linked thread on ATAG as well.
General observations and notes:
1) I tried the 111P some time ago, when Bliss wanted volunteers to test the mission on ATAG #2 before he moved it to ATAG #1. It seemed like all of its compasses are bugged/reversed: the magnetic on the right cockpit wall was acting all weird but the tooltips were giving a proper reading, the repeater was not aligned with the magnetic and everything was backwards.
Now it was late and i was a bit sleepy, but i think i wasn't imagining things. Can anyone confirm this? Maybe it's just me and i have a corrupt file or something, in which case i will do a file validation through Steam.
2) Last time i tried it, the bombsight tracks correctly for the correct TAS and altitude, but it's true that it drops a bit short. I don't know the effect of the workarounds you guys use because i haven't tried them.
As mentioned in the ATAG forum's thread that's linked in the OP, keep in mind that altitude and speed are interconnected in regards to the effects they have on a bomb drop: you can fool the bombsight into a correct drop by using incorrect values if you have the right combination and that's probably what Keller is doing.
In that sense, it might be better to use actual values for altitude and tweaked values for TAS, because the speed scale is bigger: to bomb from higher altitudes you'll run out of available altitude settings on the bombsight, so it's probably better to tweak the speed.
If what jimbop says in the ATAG thread is true (that they have mixed up imperial and metric units in the sights), then maybe the solution is much simpler: just convert kmh to mph and use that value.
One question on this though: do you use mph IAS or mph TAS?
I would test everything right now but i have an exam tomorrow morning. If you guys can help out so we can come up with a complete checklist, we won't only be able to bomb accurately but also pinpoint what the bug is.
Thanks for the help thus far and keep up the good work
P.S. For some reason i find the course AP harder to work with than in the 110. Maybe it's because the 111 is slower to respond to control inputs. Can you guys confirm that a 5-7 degree offset between directional gyro and selected heading is needed to keep it level when engaging the AP?
Another Edit: There's are carat-shaped markers on the bombsight reticule that tell you when the drop occurs. These are blurry on my screen because my low RAM doesn't let me load the full size textures (even when set on medium), but still visible. These were present in IL2 as well and worked the same.
I think i remember how it works, feel free to test and confirm if it holds true in CoD.
So, open jimbop's video here, pause immediately and go to a high enough resolution:

The double triangle marker (one solid yellow and the other just outlined) you see next to the outer curved scale is moved around by changing the bombsight angle. Essentially it's the distance to target,calculated correctly when the correct altitude is set. Essentially the sight does trigonometry for you, it knows the angle at which it is pointing and your distance above ground, so it calculates the horizontal distance.
There should be another single, solid triangle marker visible at the bottom of the scale marking how far away from the target you need to release to get a hit. This is also calculated based on your altitude and speed.
When your distance from the target matches the required distance to release, the bombsight drops. You'll see now that when engaging automation, the double triangle marker starts to move down the scale, showing how the distance to target decreases (assuming the sight is well calibrated and tracks correctly). When it coincides with the single triangle marker, that's when your bombs release.
You can also use this knowledge to do partial drops. If you manually track a target by moving the bombsight angle down as you get nearer to it, the double marker will also move down. When it coincides with the single marker you can drop a couple of eggs, then do the same for another target further on down. Not very useful for carpet bombing and certainly not until we iron out the kinks in how to work the bombsights accurately, but if we get there you could for example drop a pair of 250s on one hangar and another pair on another hangar at the other end of the field.
Hope it helps
I don't know how much of this is accurate for CoD, but that's pretty much how it used to work.
