An example:
Position: 5 checkers on the 1-point, 4 checkers on the 2-point. 1. Pip count: 5x1 + 4x2 = 13 2. epc: 4.410 (expected number of remaining rolls) * 8.167 = 36.02 3. Wasted: 36.02 - 13 = 23.02 Useful articles about the Effective Pip Count are available at bkgm.com: https://bkgm.com/articles/EffectivePipCount/ https://bkgm.com/articles/Zare/EffectivePipCount/index.html n Ian From: Christian Anthon [mailto:[email protected]] Sent: 15 January 2020 08:46 To: Ian Shaw <[email protected]> Cc: David Klausa <[email protected]>; [email protected] Subject: Re: EPC correction If somebody rewrites the text, I should be able to update the pages.

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.
