Instructor #1 routes for entry at about 12:00. I thought I'd share 'em. Enjoy soloing this one. Don't need movement speed boosts, just run past those maroliths.
There is no data. But! The Burrow Investigator says in the mission description dialogue that what time you enter affects the layout. Most people just skip that dialogue. ^^
What does need to be tested is what the time intervals are.

Last time I went in with a group I misread the little green arrow and cost us a clear. I went back in later and checked it. This is this product of that screw-up.
If these are indeed based on time of day then this will be very useful in getting my mule this clear, this was an annoying one to do with 3 people before they made meebles soloable.
This is a good help for those in need of clear, the route that is recommended is what you should shoot for. You can try the far left entrance which is basically short cut to this route, but if its blocked you have to back track and lose a good 30sec. If left/middle are both blocked then going right/ North is most likely going to fail, just exit > re enter.
