Position: 5 checkers on the 1-point, 4 checkers on the 2-point.
Pip count: 5x1 + 4x2 = 13
epc: 4.410 (expected number of remaining rolls) * 8.167 = 36.02
Wasted: 36.02 - 13 = 23.02

If somebody rewrites the text, I should be able to update the pages.
Thanks for the report.
Yes, this is an error. I’m not sure who maintains, those pages now.

Subject: EPC correction
On GNUBG's discussion about EPC (https://www.gnu.org/software/gnubg/manual/html_node/What-does-epc-mean_003f.html),
the example of 5 checkers on the 1-point and 4 checkers on the 2-point is a typical 5-roll position. Therefore, it appears to be an error to say that the expected number of remaining rolls is 2.189. A 5-roll position is elsewhere calculated to be an EPC of
36, not 17.878. So unless I am missing something this seems to be a mistake.
