the introduction was great, the video was visually very appealing, audio is a bit under average. Topic is chosen well to fit a wider audience. the amount of math "hidden" in the video seems well thought-out for the intended audience and topic (i personally would have liked seing the full graph of the pairs (M,K) and seeing 40M being a good linear approximation for small M, rather than trial and error. i understand that the chosen approach probably works better for a general audience).

Too elementary for me. May be useful for others nevertheless.

I rated this video "About the Same" & hope that this is understood as a big compliment! I believe this is the author's first ever video & I think they did a great job. Hope they take part again next year!
