Only you can tell. (We can't look at the packets you're getting:)

of randomly getting 40 instead of just 10-20 packets in one 
particular second. A spike of 40 could be allowed, a spike 
of 10000 certainly not. ;)

Since the DROP stays at 0 for several minutes that looks fine. 
If it increased like 1-5 packets every other second that would 
point to a too low limit.

You had 3 unlucky queries between 23:00 and 23:01 (legit spike 
that got dropped), then again nothing for minutes, and then 
comes the DoS that gets dropped correctly.

I think that's okay.
