Its speed in the circuit is likely to be 130 knots
Huh? Why? I have some SR20 time, though it was a while ago (not an aircraft I want to fly ever again, either). Vs1 is 61 knots, so Vref is 90-95. No reason to go faster than that in the pattern, maybe 100 on downwind. Which is pretty much what I do in my 182 (downwind - I aim for 65-70 over the numbers).
