No test will solve this problem, however careful observations of terrain configuration with good sense of scale can help either avoid or seek low consequence slopes. Last year I think one of the Hummels found this out near Fortress and walked away with a new awareness of testing this issue.
While I think your overall point is quite valid, Mattski, your citation of the Fortress incident seems inept to me. The conditions on Fortress were deep isothermal slop and the spot where Jason triggered that avalanche was an obvious loaded convexity. I had just skied the same spot, very carefully making turns between safe spots then hiding beneath rocks. Jason did not magically hit a trigger point. He simply got caught linking turns with abandon where he shouldn't have been. I helplessly watched him wash by me from a very safe enclave of rocks.
Sorry, maybe I'm still sensitive about that whole thread, but that incident had nothing to do with a PWL and everything to do with disengaging the brain. I'm not trying to pick on Jason here; I've done the same thing myself and had similar experiences riding the slurpee-death train.
