I'm inclined now to put the slipcam style mechs in the 45+ category, since the ke required to open those is next to nil.
Actually , all expandable heads require little measurable amount of K.E. gain (in percentage terms)to actuate.
TheextraK.E. that is often spoken of (in referring to expandables) is due to the cutting area being larger and therefore requiring more energy for same penetration.
In testing we found that a jackknife style expandable needed 3# more K.E. for total actuation in comparison to a fixed head of the same size.
