of course you can always compare to yourself and others but still it will be annoying sometimes.
I agree in that at first a number wouldn't make much sense, but after a while people will figure it out, provided that the meaning of the number doesn't change in a way that makes past ratings different/inaccurate. I mean, when I first started playing online games I had no idea what ping was good or bad for a given game, but figured it out after a short while by playing games with people who had different ping times. I also had no idea what SIM meant when I first started playing Supreme Commander, but after a couple of days I understood it perfectly after playing with people who were using craptops. I'm not sure that there's a number system that we could use that doesn't involve a learning curve of some sort.
We can always explain it to people who don't understand, and this would take some work, but we could put up a table that has examples of what kind of hardware falls where, and we could also construct a table that articulates something to the effect of "a system rating of X can play a 40x40 with 1000 units and 8 players with an average SIM of X". Gathering the information for those tables using standard measures would probably prove to be challenging, however. I really don't think that those aforementioned tables would be necessary though.
Of course on smaller maps with less units older hardware works fine, and the person who is hosting the game would probably be aware of that and not need to enable hardware restrictions, or even bother looking at what the hardware ratings are for that matter.
Why do I think that just a number would be sufficient for this purpose? Well, the number could be sort of like the Windows Experience Index, but a bit more accurate by using a larger number range, and configured specifically for FA, where you can get at least a general idea of the hardware that's being used and how FA will play.
As for a number not being enough; if we include too much information people will get confused, so it's best to keep it as simple as possible but still meaningful.
