I had a similar but opposite experience with one of my at120's, it was pulling 214w...at120, not at200. So I went in and dialed the current plug(Io) in scotches last pic of post#4, down equally on both drivers...I did it while plugged into my wattage meter and watched it go down. Maybe not perfect...but I can adjust the current on the drivers and get different wattage(up or down)...never played with the voltage though.I can confirm that the Area 51 drivers are adjustable, I found out my XGS was only pulling 165 watts and Jeff told me they weren't adjusted properly at assembly.
Which one is the current adjustment g? Thought about bumping mine up and throwing on the 50's hehe...
Do you know what the AT200s are supposed to be drawing? (Main production version) if not would you be willing to find out and lemme know? I'm still at 167 which STILL rocks, and I'm still pretty close to your apogee readings but if I'm off from the finished products draw I'd wanna match that.
Hope your doing well brother!

Maybe A 51 can get the assemblers to fill out a form stating individual unit wattage and affix a sticker
