I wouldn't worry about TBH. If you don't have a problem, we don't
I hope I wasn't mixing yours up with another I had open which I recall had a hump when the F1 GP was on, if so I apologise.
Yours only has a small hump yesterday evening, which you might not get on another gateway, but in general if you don't have any issue I wouldn't hop in case it doesn't perform as well.
