My understanding is that it was due to the moon being full which caused them to not have as much of an ability to observe it during the past few estimations. In an article[0] linked from the above link they state:

> Now that skies are darker after a week of limited visibility around full moon, astronomers have resumed observations

The estimates changed a lot because they were being very transparent about the information as they were discovering it.
