Tazri'a is a very small sedra; only 6 others are shorter

M'tzora has longer p'sukim than average, hence its rise in rank for words and letters

Tazri'a & M'tzora are combined in 12-month years and read separately in 13-month years

Rosh Chodesh is Shabbat either twice or three times a year. Average is 2.42 times a year. This includes a Shabbat-only Rosh Chodesh, as well as Friday- Shabbat and Shabbat-Sunday. 

IYAR’s Rosh Chodesh specifically, can only be the Friday-Shabbat type of Shabbat Rosh Chodesh. This happens 28½% of the time, divided between Tazria- M’tzora 18% of the time (in 12 month years) and K’doshim 10½% of the time (in 13 month years).

Rosh Chodesh Iyar is always the two days of the week following the first day of Pesach. Rosh Chodesh Nissan was a Thursday this year, as was the first day of Pesach. Therefore, Rosh Chodesh Iyar is Friday- Shabbat. 

(All of the above applies only for our fixed calendar. With a Sanhedrin, IY”H, the calendar will be more variable and less statisticizable.)
