Growth scans and projected birth weights

[quesadillas]

Hi,

Is there a resource anywhere online that gives you a clue as to projected birth weights based on growth scans? I've just had a 24 week twin growth scan, and I'm curious as to how that might project forward. I know twins are different to singletons and growth can slow down in the last few weeks. My first baby had several growth scans and the sonographers were quite accurate I their guesses. I'm just curious.

You can't really project from that early on as there are any number of things that can affect growth and weight gain. Also guesses from scans are notoriously unreliable anyway.
