Re: partial tongue-tie??
Based on the list above, I am not sure I would assume that tongue tie is necessarily the problem. A lot of the things on the lust can be symptoms of problems other than tongue tie- for example, loss of suction, a clicking sound, "slipping up" on the nipple, compression of the nipple, fussiness, arching, and pulling off the breast can all be associated with overactive letdown/oversupply of milk. And oversupply one matches well with good weight gain when nursing is otherwise difficult.
Did you do just one test weight at the LC's office? If so, you might want to consider getting a scale for home use, and take more measurements. A single snapshot of intake at the LC's office is not that informative, since intake varies widely from feeding to feeding. If you had a better sense of what your baby's average milk intake was, maybe you could figure out if her feeding is really being impeded or not, and that might help you decide whether or not the issue here is likely to be a tongue tie.
