Let's discuss - % power rating and % form?

[rolf]

Hi all, I'm developing a system which I hope to share the logic with soon. The great thing about it is that it is built in "blocks", a bit like object orientated programming. So, I can tweak each block until I'm happy with it. Here is where I am perplexed: What is more important? Form or power rating and by what percentage? Here's what I mean. Let's say that we wanted to rank the current premier league. Of course, the league position, especially at this early stage of the season, means absolutely nothing. In the long run it will but at the beginning it is almost meaningless. Clearly when we rank one team against another we need some form of a power rating. Secondly, form is also important. If we assume that Chelsea and Man United are pretty much equal then recent form will become significant. Sure, one team will have a home advantage, but I do also believe that form matters as well. So if you were to make your own "net ranking" based on existing power rating and form, what % would you assign to each? I am personally thinking of something like 75/25. I think the power rating dominates but form can sway it a little either side. What do you reckon?
