Actually it would probably better if you inversed the entire thing. Because if you are at x1 your team is losing. If everyone would drop down to gambesons as you advice on an already losing team, it would never win again. If your team is losing, you should gear up to enhance its ability to win, when your team is winning you can go run around in your gambeson.
In any case, I think this is a pretty useless idea. Much better advice would be to stick around 40k worth gear always to break even or gain slightly, stick around 30k gear worth for good income. Your x4 gear allows anyone to gain some pretty good cash if used all the time.
