Was the car loaded up or unloaded? I'm thinking for loaded, your adjustment is probably very close, but for unloaded, it may be on the low side.

The car was not loaded. Afterwards, i propped a yard stick on the wheel and placed a jack stand right next to the tip of the stick, some 10" forward of the tire. I loaded the front of the car and could see no perceivable movement at the end of the yard stick. Checked toe-in measurements and they were the same, 4.5 within the resolution of my measurement.

I have stiffer, shorter springs and less travel upon load. That could be why no change.

That makes sense. With my car (original springs), I attached a 4 foot metal rod to my tire with duct tape. When I sat on the fender, the very tip of the front of the rod (about 2' in front of the tire) moved a few mm, so that would mean the front of the tire was moving only 1 or 2mm. Bouncing on the fender caused the tip of the rod to move about a cm, but again, that's only 3 or 4mm movement at the front of the tire. But, enough to go into "toe-out mode" if the static toe-in setting is too small.

In your case, it sounds like you're good to go. Happy Easter!
