John,
Sorry to burst your bubble

I know you love having everything follow the rules and be exact

but yes that is exactly what we are saying. go pick up a stud that you know the part number of or measure an installed one and look in PET you will see... caused me several days of grief looking through the PET for studs that matched what I measured IN TOTAL LENGTH! I was loosing hair and I don't have that much left to begin with!!
