My guess is he forgot to put headings over the data

AL RIFFA (FR)

[Centre Of Distribution -0.35 /  Dosage Index 0.49]

Points [Brilliant 1 - Intermediate 2 - Classic 11 - Solid 11 - Professional 1]
Brilliant points from a sprinter sire in the first four generations of Al Riffa's pedigree; Classic from middle-distance 12f sires; Professional from 16f+ staying sires.

(1+2+11/2) / (11/2+11+1) = 0.486 Dosage Index .... divide the sprint sire points by the stamina sire points and you get a number

I am surprised the poster put the Centre Of Distribution number first (it is just another way of stating the dosage).

ARAPAHO (FR) 2.69; PARCHMENT PARTY (USA) 4.33; ATHABASCAN (FR) 3.00; VALIANT KING (GB) 2.56 look the least likely to stay the distance.


However, there are many ifs and buts ...

The points for a few horses are low so the calculation is probably unreliable:  
PARCHMENT PARTY (USA) only 8 points (1+4+3); ATHABASCAN (FR) only 10 points (5+5).

The Dosage Index does not tell you anything about the quality of the horse, e.g. you might think a horse with a high Dosage Index (> 4.0) would be a sprinter but he could be a very slow sprinter and a glacially slow stayer i.e. he is best at sprinting (but still terrible).

I wrote a dosage index program in 1993 but abandoned the use of dosage shortly agterwards as it is not much of a selection weapon. It might put you off one or two in a race.
