I agree with your sentiment - but part of me thinks a third GP event gets to be a lot for such young girls. And personally, i don't see why all the fuss about GPF. It feels like a somewhat hollow title - similar to 4CC title.
In an Olympic year, Nationals is more important that GPF and 4CC put together.
It is important to be ready, well rested and in peak condition for Nationals this year. Depending on the locations - and amount of travel - one of our young skaters could be a bit ragged after 3 GP events.
