On the old 373-300, you could get the ACARS to print out the G-loading at touchdown. I think the highest that I ever saw was 1.21, and that was just about a tire flattener.

Anything less than 1.05 was a good landing, and 1.01 was a great landing.

It was even sometimes possible to get a reading of 0.998 on rare occasions. Note that the G reading came from the IRS, which was located in the avionics bay, not at the CG.
