Yes, strictly speaking you are correct. But the increase in 2014 followed two years of far bigger drops in memorial attendance compared to 2011. That drop has now reversed but still represents much slower growth in memorial attendance numbers. As I said a few posts back, the best way to describe the US and territory patterns in recent years is "fluctuating" attendance patterns.
Yeah, you're absolutely right. I was just striving to trace all things with accuracy and admit when my recollection had been wrong :)
I believe 2011's memorial was on Sunday April 17. A sunday memorial would have definitely explained the uptick in attendance.
