So sorry, Gav, I inadvertently modified your post rather than quoting and replying to it. I have tried to put it back as it was, but please correct any errors I have made in so doing.
What I intended to add in my reply is (1), yes, that is exactly the sort of thing I had in mind (how much, though ?!), and (2) I don't think I ever saw the mobile pizzeria van man in Horsmonden rotate the pizzas (he definitely used a wood-burning oven) but perhaps I just wasn't paying attention.
