Lots of peer reviewed studies correlate performance to confidence which I think is broadly termed "form".
Confidence comes from being content with one’s ability and preparation, not through beating a team that is poorer the week before.
The only way the confidence can be carried over, is if the coming match up, pits you against at team, no better than the one you beaten the week before, with your own team in at least the same condition from the last game. Then you have stability, that can then be called form. However, identical scenarios never happen.
I suppose if you accept a margin of error in the match up, then form becomes reliable and then valid, and why around 1/4 of all favourites get beaten.
