Hello, just a questions about yottaa.com: on my firebug Yslow(V2) I get an Overall performance score 91 (and in Page Speed I get 95). How come on yottaa I get a YSlow score of 78?
Looks like this was a result of old data.. The score of 78 was measured on October 2nd. I hit the "Click here to re-check now" button and the score is now listed as 88. We're looking at the sub-scores now to see exactly what's different.
