Everyone is talking about curves, but no one's talking about how the axes are labeled. Based on common usage of the term learning curve, I had thought of it much like a power curve where the y-axis is the amount of cumulative effort you have to put in to reach a particular point on the x-axis, which measures mastery. Sounds like the official definition is effort on the x-axis and the total amount you've learned on the y-axis, which would indeed invert the meaning from how I've understood it.
