So how has this brilliant BCHR of yours helped in *anyway* to determine that something is perhaps not right when the BCHR hasn't changed ?

Hummm, not that meaningful in this situation is it Bob ?

In fact, in what situation is BCHR useful. Oh, that's right, not very good at answering questions are you Bob ...

Are you referring to those questions you couldn't answer ...

I suspect we're waiting until you actually know how to answer them. Might be a long time ...

I've rationally put forward my case, I've even given you the opportunity on a nice silver platter for you to put your case forward by providing a few simple little questions, to help you illustrate your brilliant use of BCHRs.

Unfortunately, you couldn't answer a single question, didn't know how to address any of the issues raised, not a one.

No soup for you Bob.

NEXT!! Cheers
