I wanted to thanks everyone for all their criticism and support for the historical ranking model I have been putting together over the past few weeks. I have listened to all of your criticsms and reasonedarguments regarding the rating of various players and where appropriate I have taken them on board and made the necessary tweeks. In doing this I have also found a flaw in some of the coding and have also rectified this. By and large this has not reulted in many changes to the historic women's rankings with the order of the three greats of the open era being unchanged. However, the changes have impacted more on the men's rankings. Many of you will no doubt be pleased to hear that the statistical case for Connors, Agassi and McEnroe being greats is now much stronger. Also in keeping with your opinions is the case now loooking weaker for Mats Wilander, although he would still be in the top 10. Probably less popular judging by the the opinions I have read is that these changes also have the effect of strengthening Ivan Lendl's case for greatness, while Roger Federer still has a little bit to prove before he achieves absolote GOAT status. Special thanks to Moose Malloy who has posted in response to my points on several occasions and always makes a good contribution. Thanks all.
