Looking again, that number for last season 2021-22 is misleading as it doesn't take into account the -12 for Derby and -6 for Reading so without those it would have actually taken 47pts to survive.
At this stage, this season in terms of the top 2, playoffs and mid-table points are very similar to last season so I'll reiterate, I think around the same number of 47 will be needed (or maybe 48 as this season there is no Barnsley/Peterborough who only had 24/22pts after 35 games compared to Wigan/Huddersfield 32/31).
