I couldn't find much info about the blind time and update rate of analog scopes and how they compare to the latest digital scopes with Max. >100kHz waverform updates.

In summary of this measurement I would say:
-This analog scope kept going until 1µs/div while the DS2000 starts breaking down earlier at 20µs/div.
-This analog scope has a max. of 511kHz waveform updates, that is less than the new one from Agilent with 1000kHz. (The DS2000 has a max. of 50kHz 1/10 of the Analog one)
So it would be interesting to add an 1000kHz Digital Scope to this graph.
-This analog scope is setup so the blind time in never getting close to 0% (sweep of 12 div, 10.2 div visible)

About the DS2000:
The waveform update rate is from the excel file from marmad. (smallest memory depth)
About the Tektronix 2465:
The blind time of 14% is about 1.8 divisions, or with other words one division left and one right of the screen (visible part is 10.2div)

Not everything that counts can be measured. Not everything that can be measured counts.

You want to know what is a "digital" scope,go to XY mode... AARRRGHH!!
Thank You, for all earth.
