Amp Davids post got me thinking I do that too much but something bothers me, I expect I will have the answer in a split second..;)

Setting aside the 17th rule, assume an old 16th Bathroom, 415.2.1 states how to cross bond correctly between fixed equipment and exposed/extraneous conductive parts, now I know earths have a common connection at the board but if say for example you did a Zs test on a final circuit feeding fixed equipment in the bathroom and it had a bad CPC connection somewhere would this cross CPC connection to another final circuit give you a false result ? I.E. you would get a reading using the other circuits CPC ?

Yes....but a bad cpc connection should be picked up by R1R2 tests before supp bonding is connected...(in theory;))
