...Average shot speed in gameplay appears to be a bit too high...

Here, I present to you a screenshot of a calculated shot speed from a game of Play Now (Offline Versus).
For reference on the x and y coordinates - the coordinate (89,0) is where the net is centered on the goal line. the coordinate (25,0) is the beginning of the offensive zone from the blue line. any x-coord above 89 would be a shot taken from below the goal line. the y-coord ranges from -42.5 to +42.5 , the width of the ice. The t is the difference in time between two spots of the shot (x0, y0, t0 is just after the puck left the stick, x1, y1, t1 is just before the puck came into contact with the goaltender), and displacement measures how much distance the shot covered between the two points.
Now that I have that out of the way, this snap shot was taken by Taylor Raddysh - who has 87 Wrist Shot Power, 88 Strength, and 88 Offensive Awareness. This shot was also taken just seconds after a zone entry - no pressure gauge impact here.
This was with Base Sliders...NHL.edge reports that only 3 forwards have even sniffed 100mph with a shot so far this season. Each of Kapanen, Tage Thompson, and Owen Tippet have 1 shot of at least 100 mph. That is 3 shots out of over 31000 recorded shot attempts this season.
