Example:
in map A you get 100/20 k/d, in 30 min
TSP given = +0,1
in map B you get 100/20 k/d, in 30 min
TSP given = -0,1

So it seems that not only kills, HS, hits, etc influence TSP but also the kind of map :s.

It just 'feels' like it, don't know if it is true :p.

ps.: ah so other players are taken into account now too , good.
