to my knowledge, the top servers average 1st serve speed is around 125~130mph at best :

You can notice that the fastest serve of all these matches is 144mph. 2nd fastest is 142 and 3rd is 138.
Serves above 140mph are very rare.
It seems the serve averages & fastest serves mostly disappeared since 2 years ago (cannot see them on the Wimbledon nor the ATP websites), so it's hard to find a lot of these stats. Thus if you have more, I'm interested.
I just did a 3-set test with a 100% serve 215cm tall player in the Training Club and got a fastest serve of 141mph and an average of 128mph, in par with the stats above.
Your player may have had a lucky match in your Training Club test.
Note: you linked files on your PC, so they can't show online.
I'm considering adding a Talent that would lead to a few very fast serves per match, but it might not come before a while.
