Close 72, except that flat armor reduction (sorry i didn't notice that corki had flat armor reduction as opposed to flat pen) is applied first. So you are right with point 1, but not quite with point 2. So any flat armor reduction increases the armor equvalence between 2 items by that amount. I.E. if Corki has 40 flat armor reduction, then the point at which LW finally penetrates more armor than the BC is 140 armor as opposed to 100. It looks like this:

[(Armor - flat reduction) * C% reduction * C% penetration] - flat penetration

LW: (140 - 40) * 1 * 0.65 = 65

BC: (140 - 40) * 0.75 * 1 - 10 = 65
