I had a Caldwell read 1456 fps on a load that was about 1100 fps under low angle Winter light with some tree cover. Overcast seems to work better than low angle sun.

Mal Paso means Bad Pass, just so you know.
As has been pointed out, lots of factors involved in chronographing loads. I use the .22-shooting method myself, just to make sure the chronograph (Labradar in my case) is awake and set to the right ranges, then I trust it. This is akin to the question of why a particular mold doesn't cast the "correct" weight.
