A member on another forum mentioned Jeff Cooper's Failure to Stop Drill. Not sure how I missed this.
I conversed with a Gunsite alum who checked his notes for the range, 7 yards. For "basic" I picked 3 seconds from the holster; for "advanced" I used Gabe's pin times from the F2S string of his Technical Skills Tests.
