No way ACK is busier than Hanscom on average year-round. Sunday afternoon
high-season I could see it peaking pretty high.

Why do people have an issue with ACK going Charlie? It's an island twenty
miles offshore which is already controlled. Doesn't seem like anybody would
be losing anything in the process. I fly around and into Class C fields in
New England all the time and other than calling in ten miles farther out
than with a Class D field it's no big deal.
