I ran out of fingers and toes, but a very rough count from their donations page was about 750, updated in Feb.
Probably meaningless, only they know. That $5800 per pilot figure might reflect money's still owed. Again, no accounting outside their inner circle, for all these years.
Both sides will eventually pay their bills with donations and awarded monies. Don't see any of this reflecting a lack of will on either side.
Collections going forward might be affected as folks on either side are unhappy with the SLI results.
And no doubt the West has done an outstanding job in collections and participation. That is a fact.
