Add an explanation of the outline styled numbers to the graph legend
I just signed up and I've noticed that my weight loss graph has two numbers in outline style on it: "$0" above the YBR, and "10" below it. I can figure out that the $0 is because I don't have a pledge involved, but I haven't been able to make sense of the 10. The legend explains data points, the YBR, the akrasia horizon, the rose-colored dots, the skinny purple line, and the turquoise swath, but not the ghostly text.

Ah, good catch! We're working hard to revamp that and make it moot but I'll explain it here in the meantime: It's the number of days starting tomorrow that you can get away with not reporting anything. So it's similar to the countdown timer, but more conservative since it isn't live-updated.
