Yes, thats correct, so to actually answer the question I asked then......
Which was IIRC more along the lines of:
If on a fairly hot cam you have the timing of the cam moved so its overlapping the exhaust cam, and the timing of the cam moved so that its got seperation from the exhaust cam (and hence the valve still open long after BDC) which of those two will help to prevent surge and WHY?
