Tessitura Analytics - Help me, I'm training people! Aka, what questions have people in your orgs had about it?

Hi everyone!  I'm posting this in multiple forum groups to get as much feedback as possible. 

I'm working on putting together various Analytics trainings for my team.  We just went to v15 in Test this week, and plan on moving to Live in early April.  My plan is to have the following trainings:

-Fundamentals (basics of navigating, reading reports, and building reports – should attend if planning to attend any other trainings)

-Development (building & reading devo specific reports) 

-Marketing/Box Office (building & reading sales related reports)

-Higher Level Reporting/Finance (for those who tend to do deeper dives into reporting, and may have higher level questions they want answered) 

I'm basically throwing myself into Analytics to get comfortable with it before I start doing the trainings, but would love feedback from those of you using Analytics already.  What are common questions that people have had while learning?  Any sticking points?  Am I trying to do too much with having 4 different trainings? Any advice on what specifically to include in each training?

Gold stars to those who share the coolest things they have figured out in Analytics so far!  

Give me your horror and success stories!  Challenge issued!
