Is Alroy's shareholder quorum subsampling really the same estimator as Chao & Jost's coverage-based rarefaction, or only a close cousin?

Alroy and Chao & Jost each claim priority for coverage-standardized richness estimation, and dispute whether 'coverage-based rarefaction' is a rename of Alroy's method or an independent contribution

Alroy defines shareholder quorum subsampling as fixing sample coverage rather than sample size, and on that basis rejects 'rarefaction' as an accurate name for it

Chao & Jost (2012) call Alroy's shareholder quorum subsampling 'a different algorithmic technique' from their own algorithm, and their closed-form equation gives exact values where Alroy's and Jost's approaches could only estimate
