If possible, post a picture or two of the cam and lifters, it might help others when they are concerned about the extra few dollars break-in oil cost.
Be sure to use plenty of cam lube again and break-in oil on the next go round, and don't be worried about the rpm. Splash oil is the only way the lobes get oil, and you need as much oil as possible ASAP.
We have all been in your shoes, I am just glad you stepped up and told about it, you may have saved others the same trouble.
As for why only one lobe? The hardened surface is only a few thousands deep, it only takes a few scratches to get under it and then it snowballs from there.
