That is also true for the rest of us here, we **do not need to discuss** one criticism after the other. I prefer someone help me to **produce** something new than constantly criticize my every words.

To be very clear with you and everyone else here, **with the exception of John's comments**, the discussions here are opinions or experimental thoughts. These discussions are not laws of nature and most of what is quoted as fact or data need to be revisited again and again for their veracity.
