I'm not entirely sure, but I think additional diffusers could help with airflow. I saw a similar question about HVAC distribution in our practice tests.

An underfloor distribution system could also help prevent this problem by providing more even heating throughout the space.

A punch list? More like a punch in the gut when you realize your HVAC system is underperforming. Commissioning is the real MVP here.
