[Power Quality] - Is this normal?

Is this normal?

I have had some appliances die over the last few months (dryer control boards (2x) Coffee Maker and a Fan) and got a sense to help me sort out the power quality. Now I am looking at these graphs and am unsure if this is normal or not. I regularly see light dim for a second, have fans slow down, etc during these dips. I am in a house built in the 1960s, towards the end of the line in my neighborhood. This is SDGE in San Deigo. They came out and re-terminated me to the main lines weeks ago but it hasn’t changed anything,

Looking at these pictures. It certainly looks worse than many other pictures up here but I don’t know if it is out of line.

Thanks for your thoughts!
