Something to consider is Altimeter QNH setting. Given that the Sim default QNH is unbelievably low at around 995mb to 997mb (normal standards is 1013) this could result in significant altitude related errors unless you set the altimeter correctly before take off. Any error works out at around 30ft/10m per mb error.

The errors induced are 2 fold. Any altitude error will affect the TAS calculation (Minor) but will also affect the Bomb range (major) since you would be releasing from a false altitude though all your Bomb sight settings appear correct. A 10mb pressure setting error results in 300ft/100m release altitude error .... that will result in a HUGE bomb range error in Level Bombing

Solution is to Reset the altimeter on every flight. This can be done by setting the airfield elevation to its correct value before flight. This will then result in the correct QNH (Pressure setting) for the map. As you will see its always in the region of 995-997mb. PDF in the attached zip file has the exact airfield elevation for each airfield in CLOD taken from inside FMB

Also don't forget the Height setting is height above target not Altitude. So it needs to be:

SIGHT SETTING = ALTITUDE - TARGET ELEVATION
