So if no holds (QC, fixes, etc.) then only takes 2-3 days to go from in production to built. Mine went into production mid-February and took a month to show as built. There have been lot of people with Jan/Feb builds with similar status and FP has no details as to why. Hence "in limbo". Others with March builds went right through from in production to build with no delays....one posted "rumor" was that whatever the hold was for got fixed so no issue when came off the line. That is my undersanding, but sure someone will disagree with me.
Now if this is ur first new Raptor and u are getting and R....then forum rules require you to have more patience.
And if u have an ETA, but neither Ford website nor FP nor dealer shows built and released to ship, then that ETA is probably bogus. I had an ETA of early March, then went to ETA Pending and then today's update.
Hope that helps even though you probably did like my answer?
