I use a couple of machines at work, that have Centroid controls and with them, if you either spin the MPG hand wheel or press the INC Jog button too fast, the control just ignores the extra pulses, until the input rate is slowed down. With this, you don't get the continuing movement after you've stopped spinning the hand wheel, whilst all the buffered pulses are used up.
Although I use Mach4 at home , the Centroid handling of MPG and INC inputs, always struck me as to be the most sensible and safest way.
I went with Mach4, well before Centroid Acorn was introduced, otherwise I would also be using Centroid at home.
