I have a TM-1 that I've used for about 8 years and have used the conversion table that came with it. I don't fret too much about the numbers- I just make sure it's around what the rim manufacturer recommends and the tension is consistent. I recently downloaded the table from park and the numbers are different:

I can't imagine they'd change the TM-1 (without renaming it, say TM-1.1 or something). it's only off by about one unit so not a big difference but just curious what others thought/ have noticed.
