That’s because the “10x” is an order of magnitude difference between the best and the worst, not the average.

Fair enough. In that case, I would expect a multiplier much larger than 10x. :-)

Definitely encountered folks who fail on FizzBuzz and similar problems.

Note that the worst doesn't even finish so the difference is infinite. 10x is the difference between the fastest and slowest of those who could complete the project.
