Here are two interesting scientific items which may help to improve your rankings: red shirts and bright lights measurably increase performance:
Ever noticed how the Chinese team’s primary playing shirt colour is red? Well, perhaps they have accidentally (or purposefully) chosen a colour that actually makes them more likely to win.
British anthropologists Russell Hill and Robert Barton of the University of Durham in England studied the outcomes of one-on-one combat sports such as boxing, tae kwon do, Greco-Roman-wresting, and freestyle-wrestling matches at the 2004 Summer Olympics in Athens, Greece.
In those sports, Olympic staff randomly assign either red or blue clothing to competitors. When otherwise equally matched by their opponent, athletes wearing red were more likely to win.
On the subject of lighting, the author cites a German study of the influence of light levels on athletic task performance. Humans exposed to higher light levels – such as the regulation 1,000 lux at the US Open – perform noticeably better on athletic and endurance tasks.
