(I'll try to describe this simple by saying nothing)

very simple indeed.
Did you select your batch to get 9.99998V or was it just luck?

Yes, I selected that one from a batch of 110.

Ups a lot of job to check 110pcs  :-// and not cheap any more compare to TiN LTZ1000  :palm:
what the average of the rest ? lets say 4pcs from random batch
If You don't mind to turn it on for a long time to see drift after let say 3 month, please.

It took me about 2 hours checking these. The voltage accuracy of these batch is very good, most of them are within 9.996V to 10.002V bracket.
I'll parallel 100 of them to get the smallest noise for solid state voltage reference, better than 10 LTZ1000 in parallel.
