If it is then your last flash test was http://tbb.st/149365563504505628812
and an early May test with the new tester was http://tbb.st/1493972752109476155
One of the changes has been the removal of some of the smoothing that was applied to the Flash figures, so you get a slightly more up/down effect when the test is running. So might be able to say speeds are perhaps 1 Mbps down in comparison to the old tester, but would need many more tests and do some by hand comparisons of the data to absolutely confirm.
Change is always a shock, but with flash becoming increasingly difficult to keep working and the security issues meaning browsers would block it at time and combined with all the other changes to site infrastructure it was time to leave flash behind, just like we left java behind some years earlier.
