First, just to clarify why it is an issue to not drop your ratings in Sweden this year... We have now begun to use a three-stage registration process for the national events. You have to be 975+ MPO to be able to sign up at stage one, a week later registration opens for 950+ MPO etc. There is a risk that the 90-player field is filled after stage 1 or 2, hence the fear for having your rating to drop below the stage limits.
However, I fully agree that rounds can be equally or better rated in winter depending on how the rest of the field plays.
I have two questions though, will ratings be the same even if the field contains some non-PDGA members? i.e. does non-PDGA members rounds contribute to SSA calculations etc?
The other question is, since I have suffered from a "frozen shoulder" for two years, there is no way to freeze your rating due to "sick leave"? I have still played in PDGA competitions, knowing that I will get a lower rating due to my injury.
