Maybe it's obvious to people who work with charts a lot, but I had to stare at that chart for a couple minutes before I knew which axis was distance and which was speed, as the number range is identical. How about some labels? As I say, maybe people more familiar with charting than I am know that when someone says "speed vs. distance," they are automatically mentioning the vertical axis first, but I'm not trained in that.
Also, it would be nice to have that chart or a synopsis of it in the Fusion FAQ. I just read the FAQ and there was no mention of how distance affects Fusion performance. I just checked my address to see whether there was a CO nearer me than last time I checked, and had I not seen previous discussions and known that 14,700 feet is really pushing it, I would have thought I was ready to go. Perhaps any result over 10,000 (?) feet should be footnoted to call Sonic for more information before ordering.
Mostly I'm just kvetching because I'm still too far from a Fusion outlet to be able to switch to it.
