Personally, I like to participate in the group competition as it is so much fun and you know where you are on ranking. What strategy is working and what not and then you put you think caps on in each and every match in order to get the best of the points in that coming matches and also to move ahead in the contest. It’s challenging but you feel good when you see your improving at the end of the overall contest.
That's the good part of it, knowing that in each events you are getting familiarize and sooner or later you'll be able to find yourself building good system to enhance your chances.
It's interesting as there are many competitors who happens to have the same intent in winning the competitions. Very falttering once you able to bring yourself at the top spot.
And much better if you win the entire challenge.
