So the two older people who jumped counted toward the nine?

I went home, and recounted too. :-)
I think you must be right, and the two that jumped were considered part of the nine total required for the festival.

Yes.

1. 72 year old man (effigy)
2. 72 year old woman (effigy)
3. Ingemar (living sacrifice)
4. Ulf (living sacrifice)
5. Simon
6. Connie
7. Mark
8. Josh
9. Christian (paralyzed living sacrifice)
