Hmm I'm just going to say loose connection and ignore all of the other problems with your post. Prepare to get some criticism though.

Have you done an IR test on the radial?

Yes lower than normal readings around 47 meg L E ok >500

Have you done a R2 + RN and compared it to the R1 + R2?

Worth a try as readings like those suggest to me you've got a poor/missing CPC or neutral. Aso be worth taking the "last" socket off and testing the cables too.
