Rafal,
Here is my impression of what your film curves would look like if they did not include flare.
I compressed the Log E scale in the toe by taking what I thought was a reasonable speed point.
Using that as if it was equal to EI 320 which is by definition 2.6 Log mcs.
Add 0.4 Log E flare to that = 2.2 Log mcs.
The difference (arithmetic) is 0.0038 mcs.
I then built a compressed scale by adding 0.0038 mcs to each 0.1 log increment going from the speed point to the right until it stopped being significant.
Some example values:
2.6 Log mcs + 0.0038 mcs => 2.2 Log mcs
2.5 Log mcs + 0.0038 mcs => 2.15 Log mcs
2.0 Log mcs + 0.0038 mcs => 1.86 Log mcs
1.5 Log mcs + 0.0038 mcs => 1.45 Log mcs
1.0 Log mcs + 0.0038 mcs => 0.98 Log mcs
By 1.0 Log mcs the difference caused by flare is 0.02 Log mcs which is insignificant to me.
