Look at the TER Instruction Manual up above and click on the Abbreviations. I look at that all the time, I will never learn all these. Hope this helps you.

Hi race-
means "your milage may vary" - i.e. your experience may not be the same.  Go to faq for newbies board, click "ter instruction manual" at top- lots of good info, including two links to decipher all the acronyms.
