Yes, I think this is the problem. I believe the intent here was to say that a sender SHOULD NOT do more than IW as an upper limit on bursts without recommending that as the correct limit for any bursting.

We can either specify that _all_ bursts should be limited to IW, irrespective of how much data is in the network already, or that bursts coming out of quiescence should be limited to IW. While I'm not sure how to change this text here, I'm trying to steer clear of saying something overly broad. (I'll suggest some text).
