The problem with NCAA equivalencies is how to weight points accumulated in non-conference games, and my point about age is due to how you statistically weight point when applying it to a projection.
I agree Connor is making certain teams look foolish (Boston and USA WJC management) and looks great, and I agree its harder to score in the NCAA. But a lot more high end offensive talent goes the OHL route, so there are more people to compare it against, the best scorers in the league out of the NCAA are Toews, Kessel, Parise, Gaudreau, Wheeler and potentially Eichel and Larkin, comparatively Kane, Seguin, Hall, Tavares, Thornton, Perry and Spezza are OHL guys, so I'd say more elite scorers have gone the OHL route, so it would be harder for a guy to post rare benchmark numbers. Connor has the highest ppg among u-20 players (best filter I could use, I know he is a very late birthday) in the NCAA (slightly ahead of 18 year old Eichel, Jadan Schwartz 18 and 19 year old years) which is very impressive. Marner 2.04 ppg in his 18 year old year has only been beaten by Sam Gagner (played with Kane), Kane, McDavid, and Cory Locke in the last 16 years the rate Marner (and Dylan Strome are scoring at) is better than players such as Hall, Tavares, Max Domi and Corey Perry.
I'm not against advanced analytic s, in many ways I think they are very useful, but I don't like equivalencies (particularly ones as complex as needed for the NCAA). I don't know how many people are baseball nerds here, but I'd much rather find something much closer to PETCOA that takes essential data (such as age, scoring rate of league and QOC) to create a profile then project from there, raw equivalence numbers do not attempt to do that. For example right now Connor's raw numbers are better than Larkin and Eichel as a freshman, but the metric does not take into account these guys did it at a younger age. Or in the case of someone like Matthews trying to apply the equivalent rate from the swiss league probably drastically underrates him.
Also, a quick question for those who closely follow NCCA Hockey, I remember someone saying earlier in the year this was a down year for the Big 10 does that still hold true today? Just looking at the rankings and it seems to heavily favor Hockey-East. Either way, what Kyle Connor is doing is beyond impressive and along with Rantanen and Colin White has probably done the most to raise his stock since the draft.
