HELP!!! SubtitleEdit, Adobe Encore CS6, possible formula for off-sync fix?

[meatboy]

Who here is really good at math?
I'm trying to import subtitles into Encore CS6, but they keep appearing off-sync and it's too much of a hassle to edit each individual line. I found this page on Adobe's website that explains how to get the "percentage" between the "Adobe time" and the actual video time to sync the subtitles properly when importing, but I cannot for the life of me understand the last equation. There was also a link for an Excel document that helps you calculate it, but the file looks like it got deleted and I'm on my last rope. Anyone able to help me out? THIS IS TIME-SENSITIVE! Thanks in advance!
