thegodfatherdany wroteRecent draws targeted applicants who entered the pool between a certain duration of time which is quite short. What if someone applied last October and is still in the pool? Will he ever get a chance to be picked?
From what I understand (though I haven't read much about it), the only new change in the draw system is the addition of the date/time that is only applicable to the lowest selected score.
So for example, from before they would say anybody with a score of 441 points would get an ITA. Now they also added a date-time parameter to the score. So in the new draw they can say anybody with a score of 439 points on or before March 2, 2018 12:00pm will get an ITA. This means that any score above 439 is immediately eligible for an ITA. However, for candidates with exactly 439 points, then only the ones who applied on or before the specified date will get an ITA.
They did this change so they can have more control over the number of ITAs issued. For example, if they select a score of 442 and only 1,000 candidates meet that score but they want to invite 1,100 candidates then they must lower the score. In some cases, lowering the score meant inviting more candidates than their target since naturally there are more candidates with lower scores in the pool.
So to answer your question, a candidate that stays longer in the pool has in fact a better chance of getting an ITA over newer candidates with the same exact score.
