Very rough because I've just thrown it together, but it was fun, so would be happy to add bits and tidy it up if it's helpful.
Results are from the main premiership website, and a sample have been checked against Wikipedia and the web archive.
very good, now if you could also do the previous 2 or 3 seasons it would be good for comparison. You did say it was fun! :)
