I like that visual - claws and fangs! For some reason, DS is not particularly competitive, at least with his classmates but that can change.

It's also kind of weird how clearly DS understands statistics from an early age. He undestands that even 99.9 percentile is ultimately a dime a dozen when there are millions of people. He is the one who pointed out to me that you can hit perfect scores on all the AMCs and be a long way from gaining one of the few slots on the USAMO team.
