On the other hand, the OWGR is biased towards European players because it weights European Tour events more heavily than they should be. If you look at other ranking systems, the Americans are even further ahead. For example:
https://www.pgatour.com/stats/stat.02675.html (Total Strokes Gained on the PGA Tour; Average US rank is 13.8; Average Euro rank is 20.7. Sergio and Oleson aren't on this stat, which means the Euro's ranking is probably higher than it should be.)

Consistent heel hits are typically "better player" misses, usually from swinging on a club path too far inside. Hard to say without seeing your swing. When i miss the center area with a driver or any other club, low and heel side is usually where i do. The result is usually some kind of a weak push or fade. If im doing it consistently (like over the course of several rounds) i'll hit the range and work on my set up and alignment. For me anyway, it usually fixes that issue.
