now duration maps looks much better. but still are decalibrated. one axis is still changed without changing values in map. leave this axis ori or change values in maps. better way to change n75 map is testing mod and making log, then if it is necessery make changes in this map.

cheers

Ok I see what U are saying. One question: How you calcute your durations?
I use this formula:
if 55mg = "a" and 60mg = "b"
than 65mg = (b - a) + b
I'm sure it can not be 100% correct but kinda works?
Now with your help i see many missed things in my file, I should start from ORI.

to calculate duration i using excell i think you too , because i checked few your new values in map and are ok ;). you changed value 55 yo 60 so you can use ori values from last column ;)
