How accurate is this? I got 22.5 mph during a soccer game?

Not sure how accurate GPS is but I had strong signal throughout the game without getting spikes in GPS data.

Over 4 seconds I averaged 21.4 mph and covered around 50 meters in about 6 seconds during a counter attack from a jogging start.

I'm usually the fastest guy in the matches I play 95% of the time but I highly doubt I'm nearly as fast as Mbappe 😂
