All we are doing it keeping the mass up in the cone area so the air pressure will keep pushing it open.

It is more a trial and error. What would be interesting is to develop a way to make the windage adjustable.

With the increased windage may come quicker advancement of the MP at first, this would be countered by makeing the MP smaller in diamiter. That is what they did with the aftermarket above. It is taller and smaller in dianiter.

How about a wedge like this. It could even then be turned to effect the rate of advancment some with out having to redo the control pressures?
