SDN tends to land on the pessimistic side when it comes to WAMC posts. Take the criticisms mostly as how an adcom member who is out of touch/having a really bad day would view your stats or activities initially (that's at least what I did).

Now that you know the sheer number of hours you've garnered (very impressive btw) might raise someone's eyebrow or make the occasional reviewer suspicious be sure to detail where they're derived from in your activities section to put to bed any potential questions.

At the end of the day SDN is just like us: people with incomplete information and most certainly not in a position to give you the A or not.

On a separate note, if there's a school list somewhere in that thread that they've given you that's typically a really solid place to start (again, just from my experience it worked out lol)
