When this list grows, you may have a chance to beat Crinacle, at least at the high-end.
I have no inclination to "grade" IEMs in any objective sense. The spreadsheet is not to be taken as a ranking in any sense beyond my personal enjoyment so that it may prove to be one data point among many for those trying to get a sense of the different IEMs out there. "YMMV and all that" is and remains my credo in this hobby
...along with "one must taste the fruit to know the flavor". As good or reliable as any descriptive impressions-- or collection of impressions from different people-- may be there is simply no substitute for trying something for yourself. Many of the IEMs I have listed as "favorites" I never would have thought to demo or seek out had I nothing to go on but graphs or others' impressions.
