No but it's only right because we're talking about it because of your book, i suppose it might be quite interesting for you to see if somebody who knows a bit like Geoff would end up at the same conclusion as you though Roy.
This thread is not about the book it's about the quoit being in danger, it's just morphed into the book now as most threads wander off the point and I've not helped in this case by keep offering titbits.
