I was just saying my experience after 30 years. Sorry to the Original Poster. I did follow up to say ignore me .
To get back on track if this chap does choose to go down the vfd route then IN MY OPINION it's worth checking Clough42 YouTube Playlist on the TECO LS510 unit. It may help.
Either way. I'll keep my thoughts to my self in future.
Don’t have to keep it to yourself, overrunning motors is OK as long as it’s within the spec of the motor and you’re not putting undue load on it. Mainly it’s bearings you’ve got to be careful with, and whether the saw itself is OK to use at that speed.
