I think this is a tricky one...
Firstly some spinners (eg Arkanoid) used gears or similar, rather than a direct method such as the Tornado, so getting the same feel will be difficult.
Also, depending what mouse driver, optics, optic wheel etc. you are using I would expect this to affect the analog sensitivity settings - ie other peoples settings might not be right for you.
I don't know but I expect most people just have a guess at this - I have only played 1 arcade spinner game (Tempest), so I have no idea how they 'really' felt, I just set them how I feel is right

BTW I seem to recall Oscar had some settings with the instructions of some spinners (probably online) - could be worth a look for a starting point...
