Personally, for 7 days there has been no peak output, it’s quite calm
Yes, I noticed it as well - it seems to look I might have been over-optimistic about the impact of Forrester Research clients. 
That would fit with load testing of clients. They tend to test with loads much higher than they actually need. The peaky behavior also kind of matches that.
I do not comment on speculations. Lets wait for this Forrester Research talk. And lets hope that it is not just talking.
