Had one on Saturday with Simon, he explained everything really well. Made a few adjusts to the bike and cleats nothing major. One of the thing to come out of it was that my legs and back muscles are incredible tight which is pulling my knees side out of line. So he sent me a load of exercises to do in order to try and resolve that issue.
Had a quick try out of the new setup couldn't tell from such a short ride, but did notice the cleats position felt a little more natural.
