jaysad,
Check your numbers again, I doubt that your SG is 1.410.
Second, I disagree with James, I would NOT add the sugar yet. This is what I would do:
Wait 12 hours after the k-meta
Add pectic enzyme, 5-6 teaspoons. Pectic enzyme will help break down the fruit and release more natural sugars. Squeeze the bag to help mechanically break down the berries some, and to mix the pectic enzyme in with the fruit really well.
Wait at least 12 hours more.
Now do your sugar, acid, and volume adjustments, after the majority of the sugars (and acid) has been released from the fruit. Some will continue to be released over the next couple of days. Luc did a nice study on this (it would take me a while to find the post...)
YMMV
