I left this crappy article up, just to point out that a steep learning curve is a good thing. An easy thing. It's not just in the realm of athletics that this is used bass ackwards, but it's popular there. A learning curve is how much you learn over time. The more you learn in a shorter period of time, the steeper the curve. If it takes you longer to learn something, the curve is flatter. If the curve is flat, you don't learn jack. And if it's a downward sloping curve (Wheeeeeeeeeeeee!) it means, over time, you're forgetting sh!t.
There, that's my logic geek of the day. It's my feeble effort to keep something so wrong from being added to the sports lexicon that makes "physicality" seem insightful.
