The ray of indefinite hope is that no new or sudden 470s dudes shall enter the pool and distress the 460s. As IELTS is totally in a standstill and ECA bodies working at their slowest pace ever (WES and IQAS have even stopped some of their prime services altogether) the next 45 to 60 days, it is typically not possible to enter the pool with high scores.
I second that there will be around 11000 dudes with scores above 460 (highest for rough calculation purpose) and 3 consecutive draws can bring the score to 460 and even lesser.
Even after this pandemic, no dude is gonna come straight away to the pool with a high score. So I would say if draws happen as devised, 460s and the high 450s can breathe now.
Since PNPs are taking in candidates as usual despite this pandemic, I seriously hope that draws would happen. Those 470s had their time. Let the 460s too have some fresh air.
Not to offend any high score dudes but talking from every 460 dude's perspective.
