I pat myself on the back for guessing pretty close. Looking at Invasion, they started work on the 4th week of March 2011. By July 12, 15 weeks later, they recorded 2 episodes. Looking at Outsiders, they started work on November 14, 2016. Fast forward 31 weeks, 5 episodes are recorded. If you think in terms of 2 episodes take 15 weeks to record in full, then they're a little ahead of the curve with Outsiders. But on the flip side for Invasion, about 31 weeks into production, they had 9 episodes recorded and 2 more partially recorded. However, this was from end of March to November 1. In Outsiders' case, they had a winter hiatus so that could have slowed progress a little. (ref: my list of production timelines) So ah, 5 vs. 9 and change. Looks a little worrisome on the surface. But we're still in a vacuum of information like how many episodes Outsiders is total so whether they're behind, ahead, or about on track is moot.
