So what's your opinion - is precision speed control useful

It's better than a poke in the eye with a sharp stick!

I understand what "close" means. That's when one outta five pulley
speeds is 600rpm and you need 500rpm. It's NOT when you need 500rpm
and you only have 3000rpm. IOW, 100rpm diff is "close enough", but
2500rpm diff is not even remotely "close".

Hope this clears it up.

I don't think precision is that necessary.
I have a 12 or 16 speed, don't remember.. I use probably 4-5 regularly.
Mostly with metal. With wood probably 3 speeds.

I think metal workers have more of a need to vary speed, as: you can
break a bit, burn it up, not have enough torque, not have enough heat
(yes I said not have enough). Certain metals require higher speeds, and
most carbide bits require higher sped.

But with wood, I'd be very hard pressed to say that even a few hundred
rpm would matter, to me it's just slow , medium and fast... (not even
the fastest my dp can go).
