Bankstown RNP RWY 11 approach on Garmin G1000

When carrying out the Bankstown RNP RWY 11C approach from the RAKSO IAF with a Garmin G1000 equipped aircraft while coupled to the autopilot, strange things happen. Fly over RAKSO at 3,700 feet and the Garmin unit doesn’t start descending to the 2,500’ SBKWI IF until there is a 3˚ approach angle. This would put the aircraft into the 2,500’ step.

In fact, if you look at the approach plate, it shows the descent should start at RAKSO from 3,700’, then go at a constant angle to WI at 2,500’. Once again, that means that the aircraft will clip the 2,500’ 20 DME Sydney Class C step. In effect, it means that the expensive and safer autopilot coupled system can not be used in this case.

Does anyone have an answer to this as to why the Garmin approach doesn't actually follow what is required in practice?
