If it slips, it's going to do it on compression, and it's going to run all the way down to that bolt.
SPC owners need to chime in, but the photos I've seen, it ALWAYS ran down to the maximum negative value when they slip, and are stopped only by the bolt hitting the inside of its travel.
I think in a situation where hundreds of pounds are on one fastener, it's probably short sighted to think that once it's slipping, it's doing any real work any more. Just my opinion though.
