I think this is a fairer and more representative list. Over the same period (since 1990), every ground that has hosted at least 10 test matches, excluding any games between Bangladesh and Zimbabwe, sorted by average runs per wicket fallen.

Still has a couple of English grounds at the top. No surprise with Lord's and the Oval which have been real roads lately, but I didn't expect Old Trafford to be up there.
