Very interesting. I think the actual thought process/visual saccades in an immediate close distance and quick reaction encounter would be a totally different process from traditional "get a tight group on paper" range work. I kinda sorta stumbled into this conclusion upon purchasing my LCP recently and couldn't quite figure out the nearly non-existent site until finding a reference to "point shoot" on another forum.
A recent friend on facebook, who is presently in Afghanistan on deployment but is also a police officer in civilian life--told me that one thing he hates to see is people who get guns and CCW permits and then think they're ready for potentially life-threatening encounters. I realized that I fit this description and need further "real world scenario" training beyond punching holes in paper.
