you want over 12v really at idle,disconnect your battery and see what the battery is on its own without the alternator or running that wants to be a tad over 12v alone.

Does the situation ever occur where you have everything on at idle ?
I suspect the answer is NO, there is nothing wrong with this alternator, they cannot do mega loads at idle speed, simple as that, doesn't cause a problem as they don't do it in use anyway.
Do the test at 2000rpm, with a FULLY charged battery and so long as over around 12.2/12.4 stop worrying, is the alternator singing, as they willoften do this when overloaded.
The 90 amp(or whatever) is a peak reading, realistically the peak is a normal continuous max output.
