I have read many posts on this site, but have never posted on this site before. However, I had a question I was wondering perhaps someone could help me with. There was some really fascinating discussion going on in this site a few years ago regarding expected k% and expected ubb% from this original post:http://www.draysbay.com/2009/7/10/944604/expected-k-s-ubb-based-upon-pitch. I know that the ek% formula was then updated in this post: http://www.draysbay.com/2009/7/21/956509/updated-expected-strikeouts-based. So my question is have there been any further updates to the eubb% formula found in the first post like there was to the ek% formula? I am not sure if the original poster is even still active on this site, but any help would be greatly appreciated as I found these posts to be really great. Thanks.
