Can someone please explain spawn cost for each game mode?

First off, I understand that Conquest is different than all the other game modes, so that will require a separate explanation.

Confrontation does not show a number, but I understand the ticket bleed and spawn cost works the same as invasion, destruction, and train escort, please correct me if I’m mistaken.

I also already understand that spawn cost varies depending on the map and faction. So it might be 10.5 in Moscow but it is 12.5 in the Pacific.

I would just like to have a better understanding.

Thank you
