Ok. Now I think I got it.
I'll use the notation "1.00" for "100%", as I think it's easier readable
- if that's ok with you.

For the selection of input videos to take for this, please tell me which
ones from Derf's collection [1] you'd like to have?

Just to avoid misunderstandings:
You mean like this?:

          coder=1; coder=0; context=1; context=0; slices=4; slices=30;
crc=0; crc=1;  min;  avg;  max
filename1    1.00;    1.03;      0.95;      1.05;      1.0;       1.2; 
0.96;  0.98; 0.96; 1.01;  1.2
filename2    1.04;    0.98;      0.65;      0.75;      1.0;       1.2; 
0.96;  0.98; ...
min          1.00;    ...
avg          1.02;    ...
max          1.04;    ...

I only copy/pasted the previous results in here to get quick feedback
about its contents/format. I was actually planning to store the final
result in a CSV file.
