I have the feeling that Gametracker.com is not tracking all of the points while playing Team Fortress 2.

Did some screenshots while playing to show you what i mean.

1. Joined the Server and my actually score on Gametracker
Team Fortress 2 Scoreboard shows = 0 Points
GameTracker Scoreboard shows = 0 Points
Screenshot: https://prnt.sc/g1h52v

2. First Round Done:
Team Fortress 2 Scoreboard shows = 96 Points
GameTracker Scoreboard shows = 23 Points

3. Second Round:
Team Fortress 2 Scoreboard shows = 180 Points
Gametracker Scoreboard shows = 66 Points

4. Third Round (Last Round)
Team Fortress 2 Scoreboard shows = 215 Points
Gametracker Scoreboard shows = 98 Points
Screenshot: https://prnt.sc/g1h5qe

5. Gametracker Scoreboard Update after 15 min
Team Fortress 2 Scoreboard shows = 215 Points
Gametracker Scoreboard shows = 204 Points
Screenshot: https://prnt.sc/g1h5vk

11 Points less, Well sometimes it's more.
I noticed it the first time after  JonasU | trade.tf played, he had ingame over 50+ Points, but in Gametracker it's only showed 29 Points.

It takes some time for your score to actually show up on GameTracker, it doesn't instantly show up.
It's a similar thing when you join a server, it wouldn't instantly show that you're online (on the server page).

Sometimes it takes more than 10 minutes for your 'actual score' (overall stats) to show up on your profile and your in-game score on the server page.

Edit - I was testing this earlier on a server, i scored 5 points and for it to show up on my profile, it took about 5 minutes.
