ok well maybe but thats the basic jist of it.  slow is smooth and smooth is fast...  why were you vertical in the keyhole...?  There is a dip in the middle of the keyhole as you bring the bike back in for the second apex, i lost my front as well same conditions as you (+throttle hanging off etc).  Brand new rear PP and a end of two season old front PP.  Im not saying it wasn't something i did, but i could be the tire age and condition as well.
