Given the 60ms delay through the frame buffers this is 160ms. CRTs also show
significant persistance after reverting from high brightness. The bulk is
dropped of after only a few ms, but a trail remains for several hundred ms.

Hmm. That's certainly a lot slower (an order of magnitude!) than the
headline response times for LCD displays.

Given the small increase in total measuring time, I would suggest 200ms as a
more conservative margin.

Yes, maybe that's needed to be safe. It does start to impact overall measurement
time though (10 - 20% of the time will be settling time).
