I'm sorry, there is zero chance this is accurate. Neither of the Flames games in China have TOI available and I've seen it with many other preseason games for other teams too.
I appreciate you posting it, but the data is incomplete, there is no context and what there is, I'm not sure jives with what we've seen (which could be caused by both of the former)... Meaning, I think it's using TOI per game but with incomplete data. That was also a hell of an undertaking by the person who compiled the data, so kudos to them too.
Speaking of Foo specifically, he played a lot when he played, but Dube has played more, he had equal or greated ice-time as Foo when they were in the lineup together, but his games with the big boys recently gave him significantly less TOI, this dropping below him in TOI/GP. And looking at Gaudreau & Monahan, its likely using stats from just 2-3 games.
