I'm pretty sure that's wrong. The curves won't "remember" the old 
linearisation - they will just be remade with the new one as if that was 
the original.

I've always found the linearisation process to be uncannily accurate. I 
don't know what calculations are being done but it works very well. It 
helps to have reasonably accurate curve set up in the first place. I 
wouldn't do the linearisation until I had got all the stepwedge points 
within about 10% of where they should be.
