after you place this file in the directed path;
you have to right click the file in OIV and then
click "edit". Once you're in the file, you must scroll down to "PlayerStatInfos"
and change "MinFallHeight" and "MaxFallHeight" to any value  you want.
unit of measurement is most likely =~ meters
My version changes the height that triggers the fall reaction to "3.0" and "3.5"
