That is an extremely useful post! It has talked me out of that extra digit, which was pretty much a "that would be neat!" thing.
6 1/2 should be plenty to see drift, things leaking, discharging etc.
I owe you a beer!

Especially since the 34461A now shows one more digit after the firmware update, we can see a drift much easier than before. For me that is probably the best feature of all the firmware enhancements.

It seems the 34461A is a little faster in getting stable and reliable readings

I owe you two beer at least, you have convinced my that my 34461A will serve me good for a few year forward and I would rather spend my money on more frequent calibrations of all my gear. A full calibration of my Rohde & Schwarz CMS 54 is > 750$ so I keep my 34461A until it breaks (or I) and spend my money on calibration and more stuff I don't need.

Johan-Fredrik, I think you will be very happy with the 33461A after the firmware update. Both of my 33461A's are working exceptionally well.
I take you guys up on the beer offer, next time I am traveling to your country.
Here is another good comparison between the 33461A and the 33470A
Conditions:
- Both instruments ON for several hours
- 10V reference on for a few days
- Both instruments on: 100 PLC, Auto-Ranging, Auto-Scale-Once (pressed once), parallel connected to 10V reference,
- Run time about 2h:18 min as shown in "elapsed time" and 2077 samples taken
dadler:
Which voltage reference are you using?
