I don't know what level of precision the altimeters are supposed to have
Accuracy decreases with range, but for comparison, a civilian Honeywell or Collins model will typically be accurate to about 2' at 500', increasing from 3% to 5% error as you approach 2500'.

Remember, the main reason for having a radar altimeter is for dealing with sink rate so you don't pull a navy style landing. They're pretty damn accurate in that last 100 feet.

Civilian radio altimeters from Collins and Honeywell are typically accurate to 2' at 500' AGL, 3% up to 2500'.
