Lizard,
Don't feel so all alone! I discovered that there are a lot of folks who missed the 'Auto Cal' option and 'manual cal' in the mains during one of the long scenarios a month or so ago.
It has been around for more than a decade as memory serves.
As to EZ Mode: With the exception of having to set a Target Altitude (which in effect establishes a height above target component for the cross hairs), both Manual and Auto can be done further out than most folks think. From what I can tell, folks tend not to focus on the EXACT Ground Tracking Point when doing Manual Cals...thus inducing Ground Speed errors in the cross hairs.
The trick for both is to make sure you are still at the altitude you calibrated at, and that you Current Speed equals Calibrated Speed at release ... after that the physics is the same. I generally get a 'Pre-Cal' shortly after leveling off, and at a speed slightly slower than I really wish to bomb. This allows me to Throttle Back {rather than trying to speed-up or hold an absolutely constant airspeed} in order to catch the calibrated speed at the target in situations where I'm being bounced approach bomb release. Its a technique, not a procedure!
The "tricky" part is to make sure you are in the correct mode when calibrating ("U") ... if not, it is self-critiquing.
Here's to better bombing!
