I intended to do this analysis when the GOL 2009 results came out, but only ended up doing it for the 9500ix until now ... I was re-motivated by all the "V1 owns GOL" and "V1 FTW, look at GOL" type posts lately.
These results combine the averages of all four V1's and the STI-R's horizontal & vertical mount runs, which were the only detectors with multiple versions/runs used in each test.
I included the 3.872 results even though, IMO, it should be excluded because it was not tested with Ka guard on ... and its data is invalid compared to the other detectors tested.
