i recently did the part 65 thing to obtain my A&P. long story short, the words, "satisfactory to the administrator" are indeed the only thing that mattered. i got my experience on the side, not via a full time job. i had nearly every hour work documented on a home-made worksheet and in dust covers in a neat little binder and a letter from my overseeing A&P/IA. he FED looked at my binder for five minutes and closed it. we chatted it up for 5 mins and he signed my stuff. professional presentation of work history helps. ambiguity is your friend in this case
