^^^ like kyle said ^^^
i think "screw up" would be an exaggeration. but with that said, the 4 hole system was in part to take FULL advantage of the flex... even if it only amounts to be a small percentage in the end.
Their inserts are also independent of each other (i.e. not a line of inserts attached to a ridged metal plate). So, even for those that don't use the 4-hole they have done what is possible to make the ride flexy-nice
