When using the scaling in AH it is a sort of trial and error in adjusting your input due to the limited visual options provided.
I would like to see a box at the bottom where it shows me the amount of input I have selected on every slider.
To save pita's regarding mouse input, these boxes should be made editable so you can put your desired value in the box of the selected slider.
Would save a lot of time and might even give you a clue what's going on.
