The correspondent proposed a complex scenario to explain how zedon Shabbos combines with shiggas melachos across all thirty-nine melachos in one he'elem, arguing that partial awareness does not constitute full yedia. Rabbi Akiva Eiger resolves the difficulty by showing that the Mishnah's seifa cannot be addressing such a case, as its chiddush must concern either he'elem zeh va'zeh b'yado counting as zedon Shabbos or ta'ah b'shiurin, thereby eliminating the correspondent's challenge to the Maharsha's formulation.
