Question about VRF Condensing Unit Inputs

Good afternoon,

I'm looking to better understand the Condensing Unit inputs in eQuest 3.65
(build 7175) using DOE 2.3.

My project has two (2) 12 Ton condensing units (same capacity) serving
approximately 40 zones.

I'm trying to better understand the following inputs (and how they relate):
"Num system (multiplier)", "Max cap/system", and "Cooling Capacity".

Per the screen capture below, is the Max cap/system input the maximum
cooling capacity of each condensing unit? So in my case this would be 12
Tons?

How (if at all) does this relate to the cooling capacity and heating
capacity specified under Cooling Performance and Heating Performance
(circled in the image below)...is that again the capacity per condensing
unit? If so, is this a redundant input to the Max cap/system input
specified above?

Additionally, can someone provide an example of when the "Num systems
(multiplier)" input would exceed 1?

Thanks in advance for any help.
