That's the thing, one ITA doesn't mean one immigrant, it could be one, two or more. RCICs are saying IRCC only need to issue ~70k ITAs this year (I'm not sure if the math checks out). Even if you set that aside, the pool will replenish very fast. Previously, EE was not that popular, now everyone knows about EE and if scoring a good CLB in IELTS is not a big deal - that's why I wonder if 450s or sub 460s will ever happen. Also, in 2019 as the awareness of EE increased, we saw scores in the range of 460s (not sure if there was a pause at the start of 2019 too).
There are 800k students that entered Canada last year, they'd easily get 460+ score too. IRCC has the pool of future 460s+ ready with those numbers. Bill C-19 is going to slash a percentage of FSW draws this year and that doesn't seem to help people below 460 either.
Finally, 7k size draws could be outliers too, compensating for past pauses and could go away.
