Can you add graphical presentation of teams' biorhythms ?
and calculate Teams Confidence because Confidence is a unique and very interesting coefficient of the fluctuation/constancy of the behaviour of each team. It will tell you which team is statistically expected to have a constant behaviour in the near future (a higher value) and which team is statistically expected to have a fluctuating behaviour in the near future (a lower value). While higher values for both teams mean safer bets, a lower coefficient for one or both teams is a sign that a surprise result is more likely to happen.
Cheers !
