Double-Dip Ratio?

[Kynch]

I was thinking about this last night.

What is the Double-Dip Ratio (DDR)? It's simply a way to know how much you've double-dipped on Blu-ray.

If you divide the number of titles you've double-dipped on, be it DVD to BD or BD to BD (like if a special edition came out) on the total number of BDs you own, what ratio do you get?

For example, I have 55 movies on BD and out of those I've double-dipped on 12 (DVD to BD upgrade).

12/55 =~ 0,218

So yeah, the higher the number, the more you've double-dipped.

I'm sorry if this is a worthless topic, but I still think it's a good way to know how many real "new" movies one has on BD.
