paulton - That sounds like a lot of work , Going back 3 days on everyone's profile will be a big job ,, I have learned from making tournaments for our club that its very important to make it as simple as possible ,
I've ran tournaments this way in my CC, it is very simple, just time consuming.
Not everyone will understand . You will get people that want to use their score on day 3 instead of day 1 because its a better score ..
What they want is unimportant, we put in the rules that the 1st score recorded for the chosen course in that 3 day window is the only one that counts. Players can use practice mode to prepare for their scored round if they wish.
I don't see a problem really, we might get some folk moaning.
I'll be happy to deal with complainers, in my own charming style. ;)
