I'm unfamiliar with the term, or what it means, though the concept seems interesting.
What it apparently isn't, is a measure of the total available or potential storm energy within a basin, which seems to me an interesting concept. I'd presume that would mostly be dependent on sea surface temperature, and SST might well be the best measure of that which exists.
If ACE is the total energy released via cyclonic storms, then the ACE:TPSE ratio might indicate future risk within a storm season for a basin.
Storm incidence is predicated on other factors, so far as I understand most especially high-altitude wind shear and total humidity. High wind shear and low humidity can both depress storm formation and development, and may have been a factor in the August lull for the 2024 North Atlantic hurricane season.
