FWIW, I think Leprecon has done an excellent job of running the numbers.
I fail to understand why many are so quick to jump on other analysis that simply makes little to no sense.
BTW, For my personal view, I think the PFS model is hopeless due to "garbage in" issues. The OS looks fairly reasonable though.
BUT, as always, people should be clear that these type number games are more for entertainment only. There are so many things that might go wrong.
