That is awesome performance. Out of the hundreds or thousands of 10811's and E1938's I've looked at, I've never seen this kind of aging. 1E-11/month is actually good for an Rb; many are worse. We barely met this number when we designed the HP 10816 Rb. Len Cutler had a cylindrical oven assembly from a 106 on display in his office. I wonder if he knew just how good these were. I think he got to exercise his perfectionist tendancies on this one, without any "supervision" from the usual suspects.
