I don't listen to Leeds podcasts but made an exception for an ASAW analysis of what it takes to survive in the PL, bits of it are mind numbingly dull, bits of it are good.
So paraphrasing Jon McKenzie, on the face of it you would think we probably need low 40s to have a good chance of survival (Sporting Index reckon 41 or 42). Things that could lower that figure, good seasons for Spurs and Man Utd, decent efforts from Burnley and Sunderland.
Other interesting snippets, the last six promoted teams, they all came back down, weren't strong candidates for survival. Ipswich and Luton, promoted too soon after a rapid climb. Sheffield Utd not in the right place financially. Southampton and Burnley committed possession heavy style of football that got them promoted, didn't adapt. Leicester financially hamstrung and lost their manager.
The season before all three teams survived.
Since then though they believe that the overall standard of the PL has improved.
McKenzie thinks we might have to accept a relegation and aim come straight back up, when likely changes to PSR will put us on a top 10 budget (more leeway based on revenues).
