Just an observation, as I've just noticed few waves of these in last couple of hours.

If they are connecting to middle nodes directly, and handling consensus weights badly, they could be misconfigured or experimental Tor clients. Or there are bugs in some Tor versions that cause small guard weights, even for non-guards. (Or they could be Tor2web or Single Onion Service clients.) A consensus weight of 1000 gets you a probability of about 0.003%. So if there are 1 million new clients, ignoring the Guard flag, we would expect 30*N of them to connect to your relay, where N is the number of entry nodes each client chooses. Recent clients that have stable connections have 2 active guards. Older clients may have 3 active guards. A client that fails lots of connections has a large number of active guards. (Recent clients try to limit this number. Older clients do not.) So having 17 active guards is not unreasonable. (It's a bug in Tor, but it's not unreasonable.) This would lead to you seeing ~500 connections at your relay.
