It's really useful, Garry. After 1 year of self-learning, you give me have a chance to review what I have been done and believe were right or not.

Can you write something about system balancing (using captube) and how to get the max cooling capacity out of the component we have? Or say how to tune a unit?

How the excessive Cond airflow and/or Evap airflow can bring the Capacity down? It looks like I have more SC, lower HP, so I can add more charge to control SH after drawing the Capacity line against charge amount. But it made no sense as I did not get what I had.

Capacity has always been a problem of mine since I started playing

Thanks, Gary
