How accurate are the timelines the dates seem to be jumping all over the place,i know that can only go from whats put in but someone could put some wrong date and that will make big changes in it?

People put in wrong dates occasionally, it is true. Quick NOA2s are usually a sign this has occurred. Since the timeline projections here are based on the timelines as entered by people registered here, they are only as accurate as the people who input them. At least, that's my interpretation.

I use the timelines to get an idea.....averages, think that is what they were met for

Ya i do to but it started out feb 2 then 17 28 now back to 19 so sometime in feb lol
