Wonder if that means they will triple all the throw bonuses
So a curveball/great throw/first throw would be 30/150/150 plus the regular 100 for the catch for a total of 430
With throw bonus' directly effecting the amount of exp. a trainer gains during this event I'm curious to see if Niantic will award trainers with a higher capture rate (than normal) if they execute an excellent or great throw when capturing a pokemon during the upcomming event.
