I know growth scans can be off, but if you had one in the third trimester, did they estimate the baby to be bigger, smaller, or close than he/she was at birth?

At 35 weeks, the tech said my baby was 5 lb 9 oz and the doc estimates about 7.5 lb, maybe 8 at birth. They measured her head and abdomen, but not length since she was too smushed up. She's probably long like me (5'11")!

I know the estimates aren't super accurate, but I couldn't find any statistical data on it.
