3 river archery dynamic spine calculator

I wish to know on the select cut measurement
there are 2    0.125
one is    -0.125 and the other    0.125

wich one means it is cut past centre

and when the say past centre do they mean by the - that the bow is cut past centre on the outside of the bow or the inside

thank you Canuck

I think that a positive number represents a dimension on the shelf side of center, or in other words proud of center (like a typical Hill style bow).  

A bow cut past center (and with a negative dimension) will have the arrow's center axis directly in front of the string.

A bow with a -0.125 shelf dimension will shoot a stiffer spine than a bow with a 0.125 shelf dimension.

OK
so all the measurement with the - are cut past the  centre of the bow toward the inside,  correct?

Those spine calculators are rough estimates at best bro.... all bows are not created equally. you can take one 50 bow cut past center that shoots a 500 spine carbon perfectly. Then another bow of the same exact weight only cut just too center that needs a 400 shaft.... Draw length makes a huge difference too....
