"So please go a little easier guy."

I wasn't criticising!
I was just pointing out for Ayman's benefit that you had just provided an excellent description in detail of what Steve had just mentioned as "Fixed Point".

I was guessing that, if he hadn't heard of "Fixed Point" before, he might not've made the connection.

Sorry if it sounded the wrong way.

Perhaps your description could go into the FAQ, as "Fixed Point" is often suggested in reply to these sorts of questions.
