yeah, not super intuitive and the legend isn't labelled.

Each coloured curve is an average moving speed in mph, ranging from 6 mph for the top curve to 12 mph for the bottom curve.   I know this is about 8 mph for me, so to hit a target date of 20 days I'd have to ride for 17.1 hours/day.  If I improve my average speed to 9 mph, moving time drops to 15.2 hours/day for a 20 day finish.  Or alternatively, if I thought I could ride about 17 hours/day averaging 9 mph, I could target a finish time of 18 days.

It's obviously over-simplistic, but I found it useful to understand scenarios in thinking about a race plan.

Nice!  I'm sure it is starting to occupy a few minds.

Attached is a little chart I made last year in preparation for 2018 (before I went OTH in late April and broke a few vertebrate, amongst other things) that I used to understand the balance between speed (mph) and riding time.  Now that my training has been reset to ground zero, I'm thinking of a training approach that will help find the right balance for me.

Anyway, I thought someone might find it useful.  I think it is agnostic to how you define moving time, could be either start to end of a day, or just actual spinning time.
