Yea I understand that, but it doesn't make sense that it would spend a long time at low lift, that would just be more pumping loss. It only makes sense to lift the valve as quickly as possible to the desired position, and close it as quickly as possible.

If we can assume Toyota measures their cam durations the same way across different models, then it should be easy to extrapolate. The 2GR cams look like about 250 degrees based on the PDFs, and the Prius cams appear to be a bit over 270.
