The 20gr result was a bit odd. It had a hi value of 1277 ft/s and a lo value of 1040 ft/s and everything in between, hence the low average.
That's a chronograph error of some sort, I'd bet.

You should be at least 10, more like 15, feet from the chrony. 15 feet is pretty much "the" standard.

The problem, as you so eloquently put it, is choice.
