Great stuff, MM.
Probably the most common problem I see on 1911's nowadays is 'barrel bump', where the barrel legs impact the cross-pin causing FTF's. A several hundred round break-in will likely beat the parts into submission, but probably not without longer term consequences. On a new 1911, especially a blued one, barrel bump can be spotted after a few magazines.
My new pistol procedure is similar to yours with a few twists, but is shorter...due to my shorter talents.
