Ok - after these latest tests, I'm happier with the newest firmware from Rigol.
![Grin ;D](https://www.eevblog.com/forum/Smileys/default/xgrin.gif.pagespeed.ic.QVVz6XIT20.png)
Rigol has improved the waveform update rates at many of the lower time base settings, with the following results:
The DSO is now able to achieve close to 50k wfrm/s (Dots mode) @ 3 different time base settings: 1ns, 5ns, & 20ns - and @ 2 of those (1ns & 5ns) using vectors.
At the other 3 lowest time base settings (2ns, 10ns, & 50ns), the DSO is faster with both channels ON (Dots mode).
With any setting (1 or 2 channels, dots or vectors) @ <= 10ns/div, the wfrm/s rate is >= ~24k.
The one detrimental (and rather oddball) change is single channel, vectors @ 20ns/div (and yes, I checked it several times): it has dropped considerably from it's previous rate (making 5ns the fastest rate for a single channel using vectors). But considering the improvements in the other rates, I can accept it.

The old wfrm/s charts in the first post will have to be updated, so I've removed the old ones for now.
