I'm currently at 98 which is my highest so far but there seems to be no rhyme nor reason as my hub profile percentage has gone down recently and I haven't published many hubs lately. I'm away in France with limited wi-fi access and limited signal when I do get it, so I don't know what's going on!!
Anyway I hope I can hit the 100 if I keep doing as much as poss at the moment. Maybe it's the consistency rather than the volume, don't know. Good luck with yours!
