I will go straight to the point.
Is it quicker to have just the ship you are looking to upgrade on your bar..
Or is it quicker to have that one ship and a bunch of dummy fully upgraded ships that share xp that is turned into free xp through GP.
I heard just having one ship on your bar gives 100% of that xp to that ship instead of sharing some of it to other ships.
Please please break this down for me.
