I've become interested in the Ti decoration and how it works. I wrote a little document (here) that I'm planning on adding information to. First: is my breakdown of the decorations accurate? I get hazy after the red/green/gold medals because I don't have that many decorations yet. Also, how many small Tetris shields do you need for the huge decoration? Somebody told me the final one is 1 million decorations but I find that hard to believe. Also, do we have any research on how the decoration system works? I've just begun to record my decoration results from games in the hopes of finding patterns but if we had better knowledge already that'd be great.
