I'd be pretty surprised by a properly applied (checked with gauge, or 
calibrated crimper) swage slipping. The cable would break first. I don't 
think I've ever had one fail, except when I used the wrong size sleeve 
for the cable, or was trying an "improvised crimper" (like bench vise.. 
please don't judge me, it's all i had at the time).  If you have the 
right dies in the crimper, it's almost impossible to get it crimped 
wrong, because the "crush" is entirely set by the notches in the dies.

The swage checker is a good check for things like "someone interrupted 
me while I was crimping" or "something looked like it was going to fall 
off the bucket, while I'm up in the swaying bucket truck in the wind"
