I witnessed a fatal Junior crash in 2007:

The report left a lot out.

Yes, full spoilers were put out in a panic move, but the small stature
student
rotated her shoulders to get them out and inadvertently pushed the stick
forward.

Ergonomics played a much bigger part than aerodynamics.

A high flare with full spoilers will likely result in a hard landing, but
futzing with
spoilers low down can destabilize a landing. I recall three landings in my
first
solo in a certain two seater not that long ago.

A low flare at good speed with full spoilers can work. Reducing spoilers at
that
point can add a few hundred yards to the landing.
