<p>Beregningen tar ikke hensyn til ujevn spillestyrke, ting som er sagt i forumet e.l.;
den antar at samtlige uspilte kamper trekkes fra en normalfordeling med standardavvik
%.1f poeng. Sannsynlighetene kan summere til andre tall enn 100%% pga. avrunding.
Tallene vil variere litt fra gang til gang fordi utregningen skjer ved randomisering.</p>
