While debugging the missing data problem, we noticed that the sharing interval for ADS-B feeders varied significantly. Some users at 5 seconds, some at 10 seconds, some at 15, 20, 30, etc. In order to help us diagnose the problem and create some consistency, we now have the ability to set a minimum interval. Currently, we’re experimenting, but if we decide to raise the interval from what we originally published (10), we’ll let everyone know.
In the mean time, the statistic most reflective of the problem is probably the # of aircraft seen.
