reason if the entered values of gray in the step tablets are:
5%=14
10%=27
20%=53
30%=79
40%=102
50%=129
60%=156
70%=180
80%=205
90%=230
95%=242

in almost all the adjustment curves the values are:

5%=13
10%=25
20%=51
30%=76
40%=102
50%=127
60%=153
70%=178
80%=204
90%=229
95%=242

Does something have to do with the contrast?
Can you vary the contrast varying only the exit value and not that of
entrance?
