78mph? Slapshot into hockey goal. You be the judge!

I have no idea how fast this hockey puck is traveling.  The only reason I say 78mph is that I shot 10 pucks into a net at a store about 16 or so years ago and the average speed was 78mph.  Some slaps went faster some slower but I don’t have a way to see how fast this shot is.  Shot taken with a Reebok 4k Hockey stick btw. What do you all think?
