Match Up 2 Question

[Wiseguy]

This post is directly related to The Match Up 2 book. Anything written here that is in blue indicates that it is text taken directly from the book. It is in my nature to ask questions when I don't understand something so please don't misconstrue my questions as contentious.

Beginning on page 27 (LaD #2, 6f D):

We will use Pretty Girl Slew as the "key" for this race, although we will change the quarter mile time to 22.2 from her third race back. The projected pace for today's race is:

22.2 / 46.4 / 111.3

I see that Pretty Girl Slew's last running line (LaD 6f D) reads:

23.0 / 46.4 / 111.3

On page 26 Mr. Bradshaw states: "Find the horse that has run the best against the fastest pace in his last race, at today's track, and at today's distance." So what is wrong with the last running line as is? Why go back three races, to a different track(OP), at a different distance (5½ f), and pull a first fraction out to use today? I understand that he wants to make the change, but there's no reason given as to why such a change is in order. And does it not seem to contradict what was just stated on the previous page?
