AC measurements are critical to really understanding your pickup design and where it sits in the tone space, and they're also good for QC.
I measure every pickup I make with a couple of key metrics and also control on these metrics.
I've never seen anything to indicate that shorts are a significant issue, or that they even occur to any measurable extent.
That being said, I have had a couple/few failures (failing the QC on the AC metrics and far enough outside the distribution so that it was clear that something very different was going on) that I don't have an assignable cause for. But we're talking like 1 per 1000, probably less since I've been doing more rigorous in line checking earlier in the process.
And keep in mind I have 6 coils in every pickup, so on a per coil basis were talking 1/10,000 or so.
