I'm guessing it's so called as only 5% of people who bought an Isis are expected to open it. I get the feeling that a LOT more than 5% of Isis puzzlers have managed to open the sphere...
Mayne it should be called th 60% club now?

I believe the actual figure (Isis puzzles solved out of all isis puzzles bought) is somewhere around 3%.
However, based on pure numbers on this forum, it should be around the 8.5 - 10% club.
Edit: Uh huh..
288 5% Club Members
3409 Registered
3409/100 = 34.09
288/34.09 = 8.448%
