Test flying is, of-course, dangerous. I might draw conclusions about the quality of Cirrus' flight test planning and practices in the 90s from that accident, but not about anything now, in their company, or the quality and safety of the production aircraft. They're just different issues, times and environments.
I did note that both with and without flaps, accurate speed control was difficult in the aircraft, and I can see that leading equally to speed control on approach. But, that's educated extrapolation, not from a specific evaluation of the approach.
