What EDU values do you mean? Charging values?Every value that you change in EDU.txt will have effect!!!

I said when you change the radius in
descr_mount.txt for tighter formation of cavalry soldiers it will not effect the values in EDU.txt.
The tightening of space between soldiers happens in EDU.txt, not in descr_mount.txt.
Descr_mount.txt only enables this option (makes it possible).
There is no limitation how many changes you can make.
Reg cavalry,auxilia cavalry,general cavalry,...it doesnt matter.
You can use different spacing for each cavalry if you like but this changes you must do for each cavalry in EDU.txt.
Everything clear now???
