In an article that I recently published on this site looking at relativity and the 47 Philimore Gardens decision see http://www.leaseholdreformnews.com/latifa-kosta-v-the-trustees-of-the-phillimore-estate-2014-ukut-0319-lc-47-phillimore-gardens/ I made a reference to graphs of relativity and the site www.graphsofrelativity.co.uk to show the general shape of the relativity curve.
I have noticed that the link did not appear in the article properly and so it is posted again here so that the link can be more easily accessed www.graphsofrelativity.co.uk
