Jeff Sackman apparently did some minor tweaks to his ELO rating. Blog post here: LINK /
I think his ELO rating is far from perfect if we are trying to come up with a predictive "Power" ranking, but it's at least a little better than ATP rankings.
I actually don't think it would be terribly hard to come up with a more predictive algorithm, and I have some ideas about how it might look. Only problem is I don't have the math/coding chops to do it myself quickly, and I don't have the time to ramp up my coding chops such that I could do it implement it in any realistic time frame.
So, yeah, beggars can't be choosers, I suppose.

Stayiing on the Sackman front, this is a good post about the down-the-line backhand, which is one of the hardest shots to hit effectively from the baseline. Soooo much easier to just pop it back crosscourt.

ELO rating
Funny you mentioned this because I e-mailed him Tuesday to see if he knows why the ratings aren't more predictive and he gave this non-answer below. Either he really doesn't know, or he has a better model that he's keeping under wraps.
