Okay, so (in the case of using a spinner for something like PP, in particular here a Tornado Spinner) does that mean higher settings of digital speed and autocenter make for a tighter response?
This seems to be the case, anyways, but not always.
Secondarily, why does older MAME have both features, while newer MAME has only digital speed?

Consider it high comedy....sincere tragedy....whatever...don't take it personally.
