Cecil,
Back in 1991 I learned how to apply the Drf variant to a paceline by a pro. He was teaching me the way to use Sartin's Tpr numbers from "Pace makes the Race" book.

Here is what he did fwiw:

17 was default as 0 adjustment
16-18 = 0 adjustment
15 = -1
14 = 1.5
13 = -2
12 = -2.5
11 = -3
10 = -3.5
9 = -4
8 = -4.5
7 = -5 Ok he stressed to AVOID like the plague using variants less than 7 or more than 27 but if I HAD no other choice than to subtract 1 fifth for 1 point from here on in
6 = -6
5 = -7
4 = -8

Use the same scale just adding instead of subtracting going up from 17
19 = +1
20 = +1.5
21 = +2
22 = +2.5
23 = +3
24 = +3.5
25 = +4
26 = +4.5
27 = +5
28 = +6
29 = +7
30 = +8

Now regarding applying adjustment to pace calls he used 60% of the adjustment(rounding to closest whole number) and applied that to 2nd call. The book said use 65% in sprints and 60% in routes but he used 60% rounded to closest whole number. He never touched the first fraction.
