It looks like the "Success Rate" graph in a deployment is incorrect on my end. Screenshots show runs on 2-9 and 2-12, none in between.
1. It is computing the success rate of 0% and factoring that into the %success when a flow doesn't run on a day
2. the days that it is showing are off by one day. My deployment ran on Friday (says it didn't), didn't run Sat Sun (says it ran Sunday)
