Sorry to hear about your illness, Mate ... I hope you're back firing on all four again now.
Maybe what the The Bold Magee missed out on was doing a bit in the "Magic Kingdom" (or perhaps a "locum" or two at the King Hussein Medical Center in Amman) ... am I right in that assumption (that you did not venture forth)?
Out there, and back in the day (as it were) we were often able to practise a bit of "innovative repair techniques" without having to worry too much about what the manufacturers might want to say. We were generally more clued up than the manufacturer's local agents, anyway. A completely different situation (and to my mind, far more satisfying) to the current (last thirty years or so) scene in the UK.
Best to get out of the NHS ... write your book (life story) and (or) do a bit of consulting.
By the way, you missed out "Evidence-Based Maintenance" ... in short, adjusting the schedule (interval) and (or) carrying out some other action(s) based upon the condition of equipment as PM is completed. You could call that "Condition-Based" I suppose ... but I believe that was to do with equipment condition as found during regular inspections ("walk through inspections", for example) ... that is before any attempt at PM.
