It's free, too. I did not realize that there would be several options.
This one does not show your "net score". You don't see Stableford points or "Bogie points" as we call them.

I think that European Courses show SSS (or CR) and Slope. Like Sippulanniemi has (yellow tees) has CR= 71.3 and Slope 137. (It's one of the most difficult courses.) I am not an expert on SSS, Cr or Slope. For hcp I use an tool from internet, that has all Finnish courses on it.

Next - let's select the best GameTracker.
It should have:
1) Groups (or a tool for a tournament)
2) Net score or stableford points - for the ranking list - or a group ranking list?
3) Free
4) lots of courses preset

After finding the best GameTracker, we can start building our Tournament!
Can be called as "GTO Golf Tour"? (We might need a sponsor to help us with the last tournament? Often the sponsors name is used in the tournee?)

We need to make a simple set of rules.
Like:
1) Cheating is not allowed
2) Everyone uses GameTrackers HCP, that is calculated by 2 - 4 practise rounds before entering the tournament. Practise rounds should be standard score you make.
3)Score that is used is "net score" = ([Gross Score-rating]/[slope*113])-GameTrack Handicap).
4) For every round you use the most resent GameTrack HCP.
5) You can enter as many rounds in one week as you want. Only the best score will be takeing part in the competition.
6) Competition start 03.00 Monday and ends 24.00 Sunday. Times are local times.

The person who wins the ranking list is the GTO champ. From the order of the ranking list players get a card to play at our real tournament. (I don't know how many players we can invite. It's something we need to arrange with a suitable course - and we should select the course together. Maybe vote from 5 different courses.)
