I don't think you understand the stat. There are hundreds of players that had a QoCTOI of between 29-30. So many players fall in that range. So yes, there actually is "much difference" between 29.83 and 29.1, despite your misplaced sarcasm.
Matthews was in the 96th percentile for QoC last season.
Barzal was in the 63rd.
A) Low St.Dev does not equal big impact for little difference; you actually have to prove it, but since you are telling people that they don't understand, you should already know that
B) "Experts" in the field, like the guy who made that graph, potentially, have trouble adjusting for QoC, and it is so small, its not even a component in the GAR model; he makes a small adj, but doesn't go into it. Yet, you fans think its as simple as popping open the internet and looking at number and percentiles.
C) Experts in the field have already explained why current versions of QoC are not good, from a statistical theory point of view
If we assume 80% of the game is at ES
Mattews' opponents played... 60*0.8=48 / 48*0.2983=14.32
Barzal's opponents played... ^ / 48*0.291= 13.96
14.32 - 13.96 = 0.36
So unless you can show me that QoCTOI% has a massive impact on skater stats using actual statistical techniques, then forgive me for thinking that second differences in ice time in competition might make M.B struggle.
Both of these guys will be near the top of the p/60 leader boards next year. They are both dominate ES scorers. Worrying about QoC with these guys is worrying about nothing.
