Realistic Autopilot Power Usage on 45' Cat ?

I am trying to figure out the realistic power usage that a typical autopilot is consuming on cats in the 45 foot range. I know that each situation is different, and there are many variable (boat, conditions, system, etc), but I am intrigued about the ranges that people are seeing. Guessing that I will be able to create an average with the data that works for my planning purposes.

If anyone can provide insight, including the system you are using, and the type of boat, with typical daily draw, it would be much appreciated.

We had an average of 7 A on a 53 footer cat (Raymarine, hydraulics, non-G model). And 3 A on a 36 ft mono (4000 GP arm). Numbers include the core and the drives.

I believe the G-models use less because they hunt less. The same nominal use but less continuous duty time.
