I believe the cutoff will be 470, or even 471.
It's important to remember that the previous draw had a cutoff of 472, and then the next one was 471. The lower the score gets, the more people are within that score. So, it's reasonable to imagine that there are more candidates with 471 than 472, more candidates with 470 than 471, more candidates with 469 than 470, and so on. Just think about... we had 475, then 472 (-3 points), and now 471 (-1 point). What are the chances of the score dropping -3 again, when the 471-468 has WAYYYYYY more people than the 475-472? It's important to manage your expectations.
So, I don't see the score going below 470 for the next draw. For last draw of October? Maybe (but yet, unlikely). The real chance is probably lying at the first draw of November, IF the influx of candidates doesn't increase.
But as I always advise: don't sit still waiting for a miracle. Start to build a plan to improve your score NOW. Not tomorrow, NOW.
I was sitting at 469 for almost 8 months, and no ITA. I was only able to get mine because in January I understood (ok, I woke up and accepted the reality) that without improving it, I wouldn't make it.
There's a real chance that the influx of candidates will met the demand of ITAs before the score drops to 468 (just like the pre-pandemic scenario). You must be prepared to have a plan B to overcome this situation.
