Openrail - Arema Turnouts - where does the dimension come from?

Question

Where does the dimension of the different AREMA turnout come from? I'm using a number 8 straight Arema standard turnout and I dont understand from where the dimension come from. Number 8 switch are around 28.8m long for Arema but in Openrail they are more around 23m long. So where does this number come from? The angle ratio is good but not the lenght. 
 
 Should I check ALL the other switch? 
 
 Please provide from where you got those numbers or verify them. 
 
 Regards

These definitions are from old Bentley Rail Track definitions, which would need some digging to find where they came in the first place. But they are the same definitions used for many years. If you can share a schematic with dimensions of the turnout (28.8m long one) we can compare it to see if there is something wrong in the OpenRail definition, or maybe it is not the same dimension or the original definitions are updated in the recent years. You can find the schematic definitions in OpenRail Designer below;
