Centennial is ~6,000’ ASL and OAT was ~15C, which gives a density altitude in the circuit of >10,500’. TAS is nearly 20% higher than IAS, then add in a little tailwind (downwind leg) and you’re down to somewhere in the region of 115kts indicated, which for a SR22 is only around Vref+30. From the spacing of the dots on the radar replay, the SR22 and the Metro appear to have being doing similar speeds, which would make sense as the Metro
AFAIK has a Vref around 115kts.
It might be a factor but it doesn’t look outrageous?
