Yes, that´s strange behavior.  Charge by the pass.
Or better yet, hook yourself up to a calorimeter, that way you know how 
much extra work those 20 cents take compared to the 10 cents. <g>

Tell that to Newton, (Isaac that is)  :)

I do that too. However, when I do a half tone pitch raise (two pitch 
raises) , it takes me longer in the first pass.
Also, when going down the bass I lower the bass strings a bit to break off 
any whatnots, wait for the little click, and bring them up.  That takes 
more time.  So the second pitch raise is quicker, because I don´t have to 
do that, and whether you like it or not, it isn´t as much movement that 
time, is it?  Anyone??

But I don´t charge extra for the amount flat.
