I put 1Lbs in the boil and going to add another 2Lbs to secondary
Ditto, but I just step-feed sugars right into the primary fermentor. This is a good way to give yourself the option of not adding more sugars if the fermentation is stuck. I'd rather have a lower ABV but well-attenuated beer than a high ABV and overly-sweet beer. That said, my brew did end up about 0.008 points high despite ramping temperature and step-feeding. Evidently, this brew takes a little finesse to get right!
