I haven't really looked, though I have two hesitations about this.
One is that I don't have the same degree of confidence in the quality of the data we're seeing in the minors. We're 4-5xing the locations and putting them in places with less on hand resources and familiarity. Not even a statcast thing but the whole Iowa velocity ordeal last month is representative. I don't think they're junk, but I also think we should be careful to attribute bedrock certainty especially if the data is outside previous norms.
The other is more important, in that while I understand the impulse and think you could build an interesting scale based on these, I don't think it's doing the same thing the scouting scale intends. Ultimately all of the statcast data is outcomes. More granular outcomes than counting RBI or looking at BABIP or errors, but still they are results that translate imperfectly when we have to understand expectations 2, 3, 4 levels above. Can I use Max EV to see if someone's FV on the power scale is too high? Probably, there are some guardrails that are likely useful checks. But the point of the scouting scale is to use information that is outside of outcomes/results to contextualize and evaluate how well certain things will translate when facing MLB pitchers/hitters, or at physical maturity, or when certain mechanics get another 12-36 months of pro instruction. Think of how often there are pitchers that see leaps in either raw stuff or performance when they learn new pitches, sequencing, or find a mechanical tweak that cuts down walks by making their delivery more repeatable. As metrics get better we need to lean on that part of the evaluation less, and that's a good thing. But I don't think that need for subjective evaluation vanishes entirely, or at least certainly not based on anything we have access to as the viewing public.
