Source FIDE Handbook "Rating Regulations effective from 1 July 2017"Section 8 of the FIDE Rating Regulations provides the following table

p and dp

I understand that dp=800 and dp=-800 are arbitary caps at the top and bottom of the table. table 8.1b

However, in relation to the other scores, what's the formula for the conversion of p into dp, and vice-versa?

As noted in the comments, the regular Elo formula almost works but does not quite work. Does anyone know what the formula is for the adjustment made in the tails?
