I don't have a lot of data to work with but what I do have is from my own site that I study intensely and I recently recovered from -50 after almost exactly 90 days. I wasn't going to remove the backlinks because they were worth more to me than the Google traffic so I just shrugged it off when it hit. But now it has recovered back to where it was pre-links.
