Correct but there aren't many. The influx is not that much when it comes to FSW only. CEC and PNP are inflating the pool at the moment and any draws happening even alternate is a good news to keep this moving. If majority of the density is at 471 472, the next cut off will be that. Just hope the density is at that and not 474 475 (which I highly doubt). As from October 2019, the cutoffs were always 469 470 471 472, which suggests that major density is around those points only.
471-472 is where inflow meets outflow. That's the point from which it'll be difficult for the cut-off to drop, even with regular draws.
Right now however, there are a lot of candidates still in 475 which is going to be a reasonable barrier to overcome.
By my reckoning, around 1,500 candidates join the pool above 480 every two weeks. In addition, above 480, around 400-500 are leftover in the pool who were FSW and didn't get called during the PNP/CEC draw. So if there's an all programs draw on Sep 2nd, half of the 3,900 invites would go to those above 480.
The same numbers (fresh joinees from last two weeks + FSW leftover from the two weeks prior) for 475 to 480 is around 700-800 based on last few months' trends.
So by the time we get to those stuck at 475 since March, there are only around 1,200 invites left. It's difficult to estimate the density at 475, but it could well be upwards of 800 as well. So once those guys get called in the next draw, only a few hundred invites will be leftover and that's likely to finish in the 474 range or if we are lucky, a bit into 473.
