But that’s the good thing about this competition: it is fair to everyone. The perfect pitch version can just use a tiny amount of additional data to decompress to the same thing, while the alcoholic will have to correct for loads of differences, making that version be much larger. This difference is the same monotonically increasing function in both cases so you can basically don’t have to care about it - you can fairly compare the lossy versions as well, you will get the same amount. So the more advanced version wins, and the competition remains fair and non-ambiguous (otherwise, is perfect pitch A or perfect pitch B had the better cover?)
