Are the responses valid?

To confirm for valid responses I compared the responses from those that provided emails to those that did not. With the theory those that would cheat would not put in their emails.

The results were very close with always less than 1 point difference (and usually less than 1/2 point) on the 1-10 scale. Thus I considered all responses valid.

Interestingly that less-than-a-point difference though small was "anti-competition" in attitude...hmmm....
