Most people who single out one past start or just the last few starts in a career normally have to deal with contradictions and its always about a runner being either In Form or Out of Form.

A Horse is only as good as his last race
or
Do not judge a Horse on ONE bad race!

I hope you see the contradiction there, right?
This is one of those things where people try to keep two opposing viewpoints in their head at one time?

Is the Horse in bad form, or was he just unlucky last race?

Is the Horse in good form, or was he just lucky last race?

He's in good form, and his bad performance last time was explained by "hidden" factors. They are hidden so well we don't know what they are.

He's in bad form, and his good performance last time was just a fluke.

The In Form form guys can explain away anything you want at any time on any Horse. That's why I love ya! Nothing better than a factor that can't be defined, analyzed, pointed out, trusted, or consistently identified. You just have to know it when you see it! But I have to admit, that certainly DOESN'T limit the IN Form guys in any way! Anything they can dream up can be justified. No numbers needed.
