Dilution question

[YukonLT]

So I brewed an extract Russian Imperial Stout two weeks ago. I missed my boil off rate, and ended up with a slightly diluted batch. The OG I was shooting for was 1.075, and I ended up with 1.070. I just took a sample and it's at ~1.028. I'm shooting for 1.017-1.020. I pitched at 70, and after 6 hours it was ripping along. After the first fury of activity, it has been working steady and sitting at about 62-63 degrees. The sample tastes pretty damn good already lol

My question is, where should I be shooting for as far as FG with the OG being slightly lower than expected? And, I'm guessing it just needs some more time now as well because I'm on the low side of the temp range. Any tips you guys can throw my way would be cool. Thanks fellas!

Take another SG reading in a week. Two days later take another reading. Don't do anything until you have stable readings two days apart. Then give the yeast four days to a week to clean up the natural off flavors of fermentation.
Congratulation on a good brew experience

Thanks. I figured more time in primary is just what I need. Still trying to decide whether to bother with secondary on this brew, or just bottle age.
