I play position locked at times with my sliders throughout the year to change it up at times and its fine. Getting the CPU hit numbers and even AI teammates is tough no matter what sliders you use.
In the NHL last season most its on average by a team was the Kings at 28, and lowest the Blackhawks at 14. So basically 42 hits in a 60 min game played.
If you can get a total of 21 or so hits per game combined by both teams in 6, 8, or 10 min periods I think that is good enough.
My last game posted at 21 hits combined by both teams in a 6 min period game. I could hit a tad more than I do, but I play laid back on d for the most part.
