I am the most credible person in the world.

Credibility is a subjective thing based on how others value your
contribution. Your own views as to your credibility are hence of little
value in this context, since I presume you are not attempting to
convince yourself.

This perceived value is dictated by a number of factors, some a

1) Peoples past experiences of your advice / work / contributions;
2) The plausibility and technical accuracy of what you say;
3) The quality of rational explanation of what you say;
4) Your ability to do all this in a polite and non abrasive way.

Hence to assess your credibility with your peers on matters DIY (or any
other subject you have a history of posting to this group about) we
should perhaps consult the group.

So dear readers, marks out of 10 for IMM's credibility?

100/10 He is invaluable in heating and water systems

I 'm sure that Fernox would work better
