I tried to explain the math behind it without calculus or too much statistics, which makes it easier to read but not nearly as in depth as the official explanation (in my opinion). It's mostly a graphical / algebra based analysis to get at the basics of what district ranking is and how your ranking at an event factors into it.

Note: I haven't taken any statistics classes and we're not yet in districts, so I'm not sure if everything I wrote is completely accurate. Please let me know if anything is wrong and I'll try to correct it.

this was actually helpful and understandable, helped me grab the actual meaning behind the inverse error function instead of just plugging it into a calculator too solve.
