In case you didn't know, you can interact with the monitor-looking thing inside the facility lobbies. The middle column says "Win streak", and I know what that means. The right column says "Times". What is that number?
On the monitors that display information in the Battle Factory, "Times" means the amount of times that you've swapped rental Pokemon with an opponent's Pokemon. It actually says "Rental/Swap" above "Times". I'm surprised that you didn't figure out that that's what times meant.
