Help with race last weekend

[patecatl]

Im new to Sartin Methodology and have been reading as much as I can. I used to just use speed numbers and trip handicap. Now I am trying to learn to use pace numbers. After looking at one perticular race last weekend at Oaklawn, I cant help but be stumped.

I dont know if its just your standard "horse had a bad day" just like humans do or if there is something else I am not looking at, or am I missing something. According to what I had, it was between 5 and 2or3. I did 5 to win and 5w3 exa. Somehow 4 came in, with its numbers I am stuck wondering if there is something I missed. Any help would be appreciate.

BTW I didnt get this card on RDSS2, I just downloaded it and doing the evaluation. I handicapped this race with my calculator.
