Unexpected Efficiency

I brewed a Belgian Triple over the weekend Hopefully something close to a Triple karmeliet, the problem is my OG should've been 1.082 well I set my system up to fly sparge intead of batch sparging I let it sparge for about one hour. Ive always set my recipes up for 75% efficiency, well my OG came out 1.092 my efficiency came out 85% I should've added some water and cut it down to 1.082 but I didn't have time to boil water and cool it, so pitched it. now i"m wondering what my FG will turn out. being a belgian triple I want it to come dry, now i'm hoping it doesn't come out to sweet I Pitched a big starter using MrMalty, now just wandering if there's anything else I can do?
"The Recipe"

5.5 Gal. Batch
12 lb. Belgian Pils.
2 lb. White wheat
1 lb. Flaked oat
1 lb. Candy sugar in boil. and I was going to add 1 lb.
in fermenter, not sure now
Orange peel and coriander in boil
Yeast was wyeast 3787

Gah, this just happened too me with a golden strong. But i just boiled down too low. Just have to wait longer for ABV to mellow id say

I just regapped my BC and brewed Denny Conn's Waldo Lake Amber. Was supposed to come in around 1.060 and the OG was 1.072. Gotta like perfect crush!

I did a 90 min. boil, started at 7 gal. finished at 5.5 gal. I should've checked my pre-boil gravity, just something I forgot. I think i'm going to dump another 3/4 pound sugar in the fermentor try to get the yeast to finish up a little lower. Will see what happens!

Ok, 3 weeks later and my fg is only 1.030 from 1.092 Not good. Thats only 67% attenuation should I try to re-pitch more yeast and hope for the best?

what was your mash temp and ferm temp?

My mash temp was 148, and started my ferm. temp at 65 then over the 2 weeks I raised slowly to 72 and now its sitting around 72 to 74.
