if our Mishnah is like R. Yochanan ben Berokah.then 16 meals are given. why? Our Mishnah is like R. Chidka, who obligates eating four meals on Shabbos. rashi says its because 2 per day for 6 days= 12 meals and 4 for shabbat. (2x6=12 12+4=16)

however my question is if she has 4 meals on shabbat, shouldn't one of the four be on friday night and three on shabbat and thus the friday night meal should count for the second friday meal(which was already counted for the 2 meals for 6 days)
