If fundraising was well coordinated, there would still be a large number of orgs raising in December. Something like a fifth of all giving in the US occurs during December. In EA the EtGers in finance find out about their bonuses in December.

However, I didn't know how many orgs were planning to raise money this December. If this was more widely known it might have made sense for a few of the CEA orgs to skip fundraising in December and raise a few months into 2016. So, the amount of coordination now is far from optimal.
