Cant say tbh. That estimate could be so off.
Like i was saying on dec thread, ive not came across 1 estimate been right or even close.
I was told going have 7lb baby, she came out at 8lb 10oz.

Pure guess. 8lb.

Yeah, apparently there's a 10% margin of error either way for the weight guess-timations

If you follow a graph up on the same percentile as your baby is now you will get an approximate birthweight.
Given babys weight at 30 weeks Id go for 8lb6oz at 40 weeks.

To add, last time I was told baby would be 7lb ish, he was 8lb13oz to the suprise of the midwives. This time my baby is already very large (2lb as of 23+4) and Im back for another scan in 4 weeks to see what he is up too growth wise. They can have growth spurts and level back out or just keep growing....its a bit of a rough guess LOL

Very similar to my baby, at 29+3 his estimated weight at that time was 3lb 5oz.

Heres the average weights for babies from 29 weeks onwards:

29 weeks 15.2 inches 2.54 pounds 38.6 cm 1153 grams
30 weeks 15.71 inches 2.91 pounds 39.9 cm 1319 grams
31 weeks 16.18 inches 3.31 pounds 41.1 cm 1502 grams
32 weeks 16.69 inches 3.75 pounds 42.4 cm 1702 grams
33 weeks 17.20 inches 4.23 pounds 43.7 cm 1918 grams
34 weeks 17.72 inches 4.73 pounds 45 cm 2146 grams
35 weeks 18.19 inches 5.25 pounds 46.2 cm 2383 grams
36 weeks 18.66 inches 5.78 pounds 47.4 cm 2622 grams
37 weeks 19.13 inches 6.30 pounds 48.6 cm 2859 grams
38 weeks 19.61 inches 6.80 pounds 49.8 cm 3083 grams
39 weeks 19.96 inches 7.25 pounds 50.7 cm 3288 grams
40 weeks 20.16 inches 7.63 pounds 51.2 cm 3462 grams
41 weeks 20.35 inches 7.93 pounds 51.7 cm 3597 grams
42 weeks 20.28 inches 8.12 pounds 51.5 cm 3685 grams
43 weeks 20.20 inches 8.19 pounds 51.3 cm 3717 grams

You are a wee tiny bit heavier for your gestation but babies have growth spurts and times of not growing so quick so its hard to guess from 30 weeks. Im 35 weeks and a scan says baby is 5Lb 9oz. from 36 weeks they put on roughly 1/2 lb a week so im expecting baby to be roughly 7 1/2 - 8lbs
