I start doing a mode for trackmania stadium called "Radar Mode" (Working Title). this is my first mode, and i do that to train myself to mode on trackmania

So instead of using "time" to see who's the best, i'm using the "Speed". When you go through a Checkpoint, your speed is saved and at the end all the speeds are summed and the player with the highest score win !
I'm doing pretty well to get the player speed in each checkpoint and then sum it. and here's what i have atm.

but here's my problem.
I'm using the "TimeAttack.Script.txt" and i'm coding over it. But i'v been trying those 2 past days to use the speed in the "system" of the game, to be really efficient and not just appear in the log ^^ (So i have to modify the "Score.Script.txt" maybe ?)
Moreover i want that the variable "G_TotalSpeed" is set for a player only, and not the entire server ! and i don't exactly know in wich script i have to find it (Event.Speed works well, but when i want to summed it or reset it to 0, it's for the entire server, so i guess i have to create a method in some "Player script" but i don't find it.
here's a capture of the script i've modified :
