Very useful chart there, Barry.

Any chance you could post this on the thread in the Useful Section, please?

I can but I am always clearing my online pictures, perhaps you or someone else could save and post it would be more likely to remain in the useful section, here is another chart with a few more on it

Cheers Barry; done.
