Text Parameter File

I'm trying to set up a parameter file for text size. I've figured out how to import and export the file. Are there any standard files available that are commonly used? My strategy so far has been to have an increasing text size for the first 20 entries that I use for silkscreen. For those entries the thickness increases as the text height increases. For the next 20 entries I duplicate the text size of the first 20 entries and leave the thickness for all sizes at 1. I use that second group for the assembly drawing. Is there a format that "everyone" uses that I should be following?
