“Calculated over 600,000 years. The rarest is miketz read 10.1% (when rosh hashana is shabnos and year is chaser.)
Pinchas is 10.6% (a leap year when rosh hashana ws Thursday)
Kedoshim is read 11.1 % of time
Tazria is slightly more at 16% (read in leap year when rosh hashana was shabbos or monday and year is chaser)”
This math has to be mistaken. Kedoshim can be read in one and only one type of year – A leap year with Rosh Hashana on Shabbos that is chaseir. Any other year, either acharei mos or kedoshim is either shabbos hagadol, rosh chodesh, or machar chodesh.
As many people have already said, Miketz is read on two types of years. When Shabbos is Rosh Hashana and the year is chaseir, regardless of whether it is a leap year or not, chanuka will start on Friday and Miketz will be the day after Chanuka.
If you were paying attention, you would have noticed that the only year we leign kedoshim is one of the two years we leign miketz. that means WHENEVER we leign Kedoshim, we leign Miketz, but we sometimes leign Mikeitz without Kedoshim. ubiquitin’s math comes out that Miketz is less common.
