Side Plate Stu Miller Calculator

[acollins]

I have been playing around with some new Gold Tip Blems.  I have been messing around with Stu Millers Calculator.  I have read through the directions and am still confused on cut to center and side plate thickness.  As I plug numbers in I see this number makes a huge distance.  So to my question.  I am shooting a Martin Hunter 45# @ 28"  Is this bow cut to center or past and what number should it have in the thickness number.  It is just the stock sideplate that came on the bow new. Below is the specs I have been using and I am coming up a good ways off.  I think it may be do the the thickness number. Unless I am doing something else wrong.
