No, it's not done. The server only needs to look at this data when the relevant city is being collected, and adding the boost. If it's your city it does it when you're looking at the things that benefit. Definitely not when the Aid button is pressed on another computer.Why polish at all in a city already at 120%? The simplest of programming can have it see polish isn't needed and to motivate instead. Only slightly more thought to programming can have it see polish will run out soon and polish before it does, leaving a city fully polished at all times while not ever polishing those never needing polish at all.
When Aid is pressed, it doesn't need to look at the city at all unless the BP trigger is keyed, and then only the building itself is loaded.
