Just had this video pop up in my recommended feed and thought some folks here might appreciate it.

Summary: Mathematician works out the average result of an unmodified d20 roll with advantage (turns out its 13.833), then extrapolates to create a formula for doing the same for a die with any number of sides. Then does the same for roll 3 and take the best - functionally elven accuracy (for d20s it’s about 15.5). Then further extrapolates for taking the best of any number of rolls.

Interesting stuff, but I think we can all agree that the most valuable takeaway here is that the average result of rolling an infinity sided die with advantage is 2/3 (roughly 0.667).
