I used to work for Kent Cam's (80's)
New & used cams were straightened to 1 thou on the centre bearing's &
centres scraped to one thou on outer bearings
then ground so base of lobe was concentric
both new & used were within 1 thou
measured between centres by hand
if they moved too much during straightening , we put a hammer thru them as they would bend while profiling
new & old were just the same when it come to weakness

Re-profiled lobes have less surface area - so in theory all being equal , will wear quicker
