Atec rookie pitching machine

[fieldzy0]

I have an atec rookie pitching machine and I don't have a pocket radar to see what the speed is. I have a dial from 1-10 and looking to see if anybody knows what the setting is to get the speed around 60mph? I would like the set the machine from 50 -60 mph but don't know what number it should be set at. Does anybody on here have one and know what the speed settings are?

thanks
