This might actually result in some really weird match results.
Not mensioning the names but all can think who this might effect.
There have been players that have been playing 4 hours in 40C degrees and not showing any signs of tiredness... Might have been in supershape or then using epo.
And if someone gets caught they get 2 year ban. Not some lame 3-6 months that does not harm player that badly. 2 years does.
Good move by the ITF.
