Sorry. Not very grown up of me. Don't know what I said to deserve the last snide comment you made though.

Me pointing out the maths things was not me pointing out the maths thing, but me pointing out the units thing. There's a big difference between 12 ft and 12m.

As to knowing answers because I have a website ... well you know how stupid that comment is don't you. It's like saying just because I've just landed a good publishing deal I know all the answers. Obviously I don't and have never pretended to. I have a lot of theories, but there's a big difference that I'm very aware of. It's a shame some others don't know the difference.

Regards

Tom
