That's almost identical jaydub. Apart from a couple of extra max yellow spikes around 2pm and my own power down at 9:20pm, the pattern is the same.
On a side note but same topic of latency patterns, do you get these odd decreasing triangles in your TBB graphs? This is one example on the 27th March:
I don't notice any issues when they happen but they appear now and again on the odd day, sometimes smaller, sometimes larger, sometime solid triangles, sometimes individual spikes spread out, but always the same downwards triangle pattern.
