We analyze Navascues-Pironio-Acin work [NJP 10, 073013 (2008)] and find an intriguing statistical interpretation of the results. Using this we suggest that quantum formalism can be derived from first principles. Namely, any theory in which a global statistical picture is achievable is consistent with quantum theory. Counter-intuitively this principle does not contradict contextuality proofs of quantum theory in the limit of weak measurements. This work also enables unifying Bell inequalities and Leggett-Garg inequalities in a single framework.
