yes, it used to be all the skaters had 3 events, one non-scoring. the past two years, i think all the skaters had only two, and now they are bringing back the third event for selcted pairs only. I think that it is better with three.
In the past, I believe that ALL skaters got 2 but SOME skaters got an extra one to make it 3. Why some skaters got 3 and not ALL should be answered by someone who knows why. I don't. It's history now anyway.
Nowadays, the rule is no more than 2 for skaters who meet some sort of World Standings criteria, I believe. There are several skaters who opt for only 1, or their Fed will allow only 1. (There have been skaters who would not accept the invitation, and did not participate in GPs.)
The Drawbacks of allowing 3 GPs
It is not open to ALL skaters
The Third GP, if it were skated the best, it doesn't count towards GPF.
Since those opting for a 3rd GP, are considered Top Tier skaters they prevent a lesser skater from a medal and also prevent the higher points they would have attained. There could be strategy here.
The Organizers refuse to accept skaters who they deem are not up to standards.
On the Plus Side of allowing 3 GPs
There is some sort of need to fill the list of entrants for each GP
The popularity of the skaters who do a third GP could bring in more money for the event.
It also allows for an additional dress rehearsal practice for tweeking their new programs.
Weighing the above, do you agree that 3rd GPs are fair to all skaters?
