Bah. I myself was rather grumpy and frustrated yesterday, so I should
be the one to apologize. I know this is a very cloudy issue with *many*
areas of potential misinterpretation -- I've posted things I've been
corrected about as well (and even argued the incorrect point ;-).

I have to agree about the potential oddness of a value of 001, with the
reserve that it is still very possible that the numbers are correct.
This may be a case where load_cycle_count's raw value may be of use --
check the values, wait for the click, check the values, and see if it
has increased by one (in which case at least the raw value is probably
correct). This can then be compared against the spec sheet.

Of course, the preferred route would be, as you mentioned, download the
manufacturer's utility and run it.
