This is exactly right. You need to be careful when using these terms or when reading someone else's post that uses these terms, because they don't mean the same thing to all people. Read on...
Here's an example where it can get confusing. When Toreby says "last year" I'm not sure if he means last Use Year or last calendar year. If he's referring to Use Year then I agree with him completely. But if he's referring to calendar year then he's actually missing a year's worth of points.
For example, I recently bought a DEC VB contract that had 2015 points banked into the current 2016 UY. It also had current 2016 points as well as 2017 points coming on December 1 of this year. To me that contract is fully loaded because it has three year's worth of points in one calendar year. So by my definition, early UY contracts can never be fully loaded because you can't get three year's worth of points in one calendar year.
Rather than focusing on terms, I think it's more productive to focus on the points that are available. Right now we are in the 2017 use year for FEB, MAR, APR, and JUN. We are in the 2016 UY for AUG, SEPT, OCT, and DEC. I would concentrate on buying a contract that has the current UY points available. If you're buying a DEC contract and no points are available until December 1, 2017, you are technically buying a contract that is stripped.
