John, I never disagreed with you. Your original conclusion correct,
however it was based on fallacious logic. (i.e. your conclusion,
albeit correct, did not follow from the premises provided.) Mr
Woodgate was able to point out non sequitur in your post as well, so
it was not a mere English misunderstanding on my part. I directly

Regards.
