TBH you should always count from full hard backwards to full soft.
So FH the -1, -2 -3 etc. This will give you the best base line -ie the needle and jet will be closed at full hard - dont force it past its natural hard point - it won't always go to the next click!
Full hard is when the shims will have an effect at full soft or probably within half a dozen clicks of full soft the bleed through the jet and piston will be taking the majority of the oil and so there won;t be much difference to a click at this softer end of the scale.
However from experience the dampers are not likely to be the same on the same click settings any way and the only way to tell if they are is to have them dyno tested.
