You are correct, Jeff.  That is what he is sa= ying.  The problem is, he is wrong.  When the apex seal is crossi= ng the plug hole, there is no compression on the intake side yet (it's actu= ally below ambient for an NA engine) and the exhaust side is at it's most e= xtreme pressure.  Look at the volume of the chambers.  The intake= side has just finished pulling F/A mixture in, the exhaust side has been i= gnited and is providing the power pulse.  If anything, some burnt mixt= ure from the previous burn is going to be pushed BACK into the upcoming one= . 

In fact, providing more of a slot might just blow the F/A mixture away fr= om the apex seal and solve half of the quenching problem.
