And I mean "basic"!!! You could make a short course last a whole day on PAUT focusing. This just scratches the surface in a little over 5 minutes. And no, I'm not suggesting to always focus at a constant depth of 1.5T... but (dot dot dot), it *is* a pretty standard rule of thumb and should work for the majority of the general cases out there.
When in doubt, run multiple groups, kids! Now go read your procedure and have a time!
