I'm seeing a "strong" systemic response at the moment, by my definition of the word.
I'm using "not strong" and "weak" interchangeably, compared to a strong effect seen with, for example, the injected tumor of the sarcoma patient. I wouldn't argue with your use of the word "strong" as you are defining it. To comment further on your post I would have to look more closely at the data you cite than time permits at the moment.
