I'll ask around, not do a full survey. I won't bet in this market.

Final tally 27 of 44 = 61.3%

It was above 70% oldest for much of the weekend. 65-70% for almost all of Sunday. 3 youngest at a Sunday evening music jam took it under 65%. Perhaps musicians are an exception to the birth order effect.
