We probably feel large numbers of 464 to 470 have entered the pool because they’re more active on forums like these. This is because they’re on the borderline and actively discussing to get as much information as possible.I wish I can see 469 or below in next draw. Large population are in between 464 to 470.
People below 464 are aware that they don’t have a chance in the next few draws thus they’re just observing.
People above 470 have little to wait and are aware that it’s their turn in the upcoming draws, thus they’re less active as well.
It’s difficult to know the breakup of people in the pool with scores between 451 - 600.
