^ Great advice if you have been driving a 172 around the pattern at a much higher airspeed than norms for the platform.
But for Mooney's...
Mooney's are an *on-speed* aircraft and will clearly let you and insurer know when excessively fast on final due to excessive float (overruns, porpoising & prop-strike due to trying to force the aircraft nose-low onto the runway) ...or your insurer/next of kin know when excessively slow. Systematically speaking, pilots who are flying Mid/Short body M20s are doing it at 100/90/80 MPH ("ish" +/- for weight). If that is incompatible with other aircraft that have a 20MPH lower stall speed and thus tighter patterns... there is one choice to avoid crowded pattern contention and that is the same thing that jets do... fly bigger pattern which allows both for airframe appropriate speeds and more gentle turns.
Making traffic and tower happy isn't killing Mooney occupants.. things like slow airspeed combined with higher rate base-to-final turns & departure stalls are definitely killing distracted pilots. So, you don't have new Mooney pilots staying off-speed in either direction for long periods as training and the laminar flow wing and slippery aerodynamics will respectively correct.... or tend to hand your wallet (possibly with your (_!_) attached) as corrective feedback. The only time that I can think of Mooney's en-masse going faster than the above mentioned speeds "in the pattern" is when they are not in the pattern and rather on an instrument approach and trying to keep 90Kts + on long-medium final for approach traffic flow compatibility.
