They vary all over the place. The ones I've bought on eBay range from "pretty good" to "darned good."
The 10811-60109 used as a reference for the first four plots achieves ~3E-13 @ t=1s, so ZC4740 is an honest 5E-13 part. I'll run that one overnight in a 3-corner hat with your two "Super" 5065As, since the light blue trace was taken with a stock unit...
