i've been wondering for a long time, say pros from china go to, say, denmark for the denmark open or something.. due to the difference of time zones of the regions, won't teh players feel uncomfortable on court during their matches? i've also made up this imaginary theory that maybe that's why some players are inconsistent, and the more they're used to teh time zones, the better their performance... for example, say a korean pro went to two tourneys, one in japan (which is near korea) and one in england (which will have much different time zone)... if they do well in japan, and do bad in england, does that mean that time zone DOES count when playing? how do couches deal with this?
