Can anyone say whether the LC blend level 

1/ Corresponds to any particular model of transparency and opacity?

2/ Can be described in units of some kind other than the LC 1-100?

3/ Might approximate a linear scale?  (Although of course these things are very trick with perceptual stuff)

4/  Gives reliably similar results across different machines & OSs?


Best Wishes,
