Matt Parker sometimes tries to calculate pi by hand. This year, he's doing it with >100 volunteers over a total of 6 days in February. The question is, how successful will they be at calculating?

Minutiae: the 3 in 3.14 does not count as a digit; as is tradition we are counting decimal digits. Only digits which are actually correct count; a final answer of 3.142 has 2 digits correct, the 1 and the 4. The 2 would be the correct rounding, as the true value is 3.14159, but is not correct.

Note the uneven bin sizes. I did this as William Shanks calculated 529 digits correctly by hand in the 1800s and Parker has stated a desire to beat the record.

The most likely resolution source for this market is a video by Parker around the date of pi day. I reserve the right to resolve in some other way, eg asking on Parker's discord, were the video to not come out in a reasonable time frame or be ambiguous.
