Hi, apologies for the delayed response. Been really busy the past couple of days.
Anyway, as per request ive attached the graphs. Hopefully this may paint a better picture. If there are other bits which ive missed out please do not hesitate to ask.
As for the power board i dont really know what work they carried out tbh, all they said was that they fixed a faulty joint. And i do believe that the power was turned of for a few houses on my street as they had dug out quite abit.
