If your uptime (or your percentage score in a class) is best understood/consumed on a chart with an origin of zero, you’re having a very bad time.

If you’re comparing your uptime before and after a fix, you’re lying to everyone by not showing the origin.

Also why are people looking at uptime unless there was an outage? At which point you do need to show zero anyway.

What you should really track and chart is your downtime.
