Yes.. which is what he's been doing and I think it's appropriate.. this is a fluid, subjective, adaptable list.. not something that is set in stone.
Considering that he just did that after including the Miracle, I don't think he would want to rescale it again
Even grades like A+, A would bring back the same debate at one point of time or the other. Numerical scores are better in that they allow a relative comparison between IEMs that fall within the same tier in terms of SQ. No matter whether the score is out of 50 or 100, it would once again lead to the same questions. Personal differences with scores will continue to exist no matter what.
The point is read the score to see which tier the IEM falls into, it's peer group, how it's ranked relative to them, BUT read the sound description, see the features (Comfort, Isolation, Build Quality) and decide if it suits you. Without a SQ score, I certainly would be lost as I cannot be expected to read all 130,000+ words to find the right IEM. At least, that's how I use this vast resource.
COSIGNED. I too use the scores in relative terms more than as absolutes.
