The “Performance Graphs” was never posted by me in FlightAware forums as J Prochazka’s “ADSB Receiver Project” thread is already in place here.
I think you got it mixed up with the manual install of dump1090-mutability ver 1.15~dev which I have posted in this forum. This is not in Tweaks thread. It is in thread Bake a Pi >> OPTION-3.
However I have posted Joe Prochazka’s script in FlightRadar24 and PlaneFinder forums so that members there can also benefit from Joe Prochazka’s work.
