What exactly does XP mean in tournaments?

[Alex_tgiu]

This might be a basic question, but I was suprised to not find it in Q&A section or the XP explanation section.
What does the XP display on a tournament mean? Is this something one can win? And is this something the organizer can set or is somehow calculated?

I'm wondering the same thing.

I have 3 insights on that - Tournament XP depends on number of participants. Winner of a big tournament gets like 300 XP.
In earlier days it seems to have been corrupted, as some people started many micro tournaments to farm XP.

So all of it goes to the number one ?
No proportional split between top ranked players?
