I'm sure a real engineer or engine builder will chime in but supposedly a vast majority of the bearing wear occurs fairly early in the engine life when tolerances are tighter and proper break in is critical, which is when you would see the highest amounts of lead and copper (in 08-09 engines) in Blackstone reports. Once the wear has occurred over time the tolerances between the rod and the bearings loosen up and the friction decreases somewhat...so less lead/copper would be spun off. I'm not remotely an expert in this area but based on the research I've done...I don't think this report can be read that your bearings are in great shape. Maybe they are...maybe they are not.
