Yes, I have just done up version 6.2 of my SOP. Showed it to my wife, and she liked it. To her, this must be it. Personally I am also quite satisfied with this version. Not only has it addressed various important issues but also presented them in the best way (yet).
There are a total of 14 versions, from ver. 1 to 6.2. Man, that's a lot. Anyway, I have started to adopt my SOP mastercopy to the requirements of the respective school. Quite a lot of work. Seems like I'm on my last mile in the application process.
