The idea is this.

Calm doesn't show off the later levels, and is pretty limited in terms of optimisation.

Total Demolition might be a tad too grindy to get into, and not too different from Crazed (the big ones being the Train level and the Library).

So Crazed is probably the optimal category for speedruns, with enough depth in terms of optimisation of movement, boss kills, etc.

All categories will be open for running. Crazed is the main Category we run and submit to marathons on the Super Nintendo Already.

Well, yes. I'm not arguing for closing off any categories. I'm only arguing for Crazed to be the default one to be displayed when one opens the Demolition Man page on SR.com.
