A Google search for "effective decision making group size" reveals as
its first hit this paper:


Which concludes, "if you’re looking for the best size for a team,
consider an odd number close to five."

Another top hit references the book, "Decide & Deliver: 5 Steps to
Breakthrough Performance in Your Organization." The authors found
that, "Once you've got 7 people in a group, each additional member
reduces decision effectiveness by 10%."

Also, even numbers (like 10) are bad for decision making. A google
search of, "decision making even odd" finds as its first hit:

This research reports, "boards with an odd number of members may make
better decisions."

So having spent a little time reviewing published research on optimal
board sizes, I respectfully disagree with your support of ARIN's
10-member board plan.
