A not-fully-fleshed-out idea related to the grosses as they stand now:
As of today, there are 21 productions playing on Broadway. Is that perhaps an ideal number of Broadway shows? Is there too much competition in the marketplace when we have 35-41 Broadway shows running at the same time, thus bringing down alllll the shows in the lower tier?"
I think the answer is yes and no.
It's simple supply and demand that, if supply drops more than demand (as seems to have happened this winter), the remaining supply will be more popular. We've definitely seen this in smaller samples before (Lion King, Aladdin, and Frozen on broadway at the same time)
However, I don't think you can make your statement as confidently when you consider the types of shows on Broadway right now. In December, almost 20 of the shows were what I'd call prestige or at least not super touristy (not exact because some fall in between). Today, that number is around 5. Meanwhile, the number of touristy shows has decreased by just 2 (Music Man and Beetlejuice). While, theoretically, it is a more local audience right now, the touristy shows are still the biggest and most resilient and they represent a much higher share of the market at the moment.
I think you can definitely say that some shows last Fall were hurt by too much competition and some shows are being helped by the lack of it right now, but Walking With Ghosts was never going to be anything close to a hit and Funny Girl isn't performing so well right now just because there's less other stuff to see.
