ZX-5 diff....again

[littlened]

Someone please help me here.

to get it so that under acceleration the slipper isn't slipping like nuts I have to tighten it to a certain point, but then to get the diffs set so that the slipper slips before they do I have to tighten them to what seems really tight.

Now when I hold the car in the air and turn one of the wheels, every wheel turns in the same direction, is this fine? or does that indicate that the diffs are too tight?

If I loosen the diffs off even a little, then they slips before the slipper, but then if I loosen the slipper a bit so that it slips first, then the slipper slips like crazy when I pull away.

Can someone just confirm that the way I have them now seems right?
