This is greatly appreciated, and something a lot of people miss! Well done, very thorough analysis! One question - why did you calculate the harmonic mean of the VMAF score instead of the arithmetic mean? Just curious, as I was under the impression that arithmetic mean was the way to go. Well done overall though!
