So you might be right that reaching the 2500 points would be very difficult or near to impossible. Foolinlove's tip is good because it is not advisable to farm for the stage that gives 1 or 2 points, as it would be a waste of time and game stamina.
An example would be the recent Halloween event, I guess not all players would be able to collect 300 spooky ghosts, 50 pumpkins and 20-30 witch hats at one week or less, even if they are grinding 24/7 on the said dungeon because of the roulette results.
