So if Rashi is 1,2,3,4
then R”T is 1,2,4,3
and Sh”R is 4,3,2,1
From what I understand, according to Rashi, R”T tefillin are not kosher, and vice versa
Is Sh”R kosher according to Rashi? Is it another way of arranging Rashi? For example, could you say that it’s still 1,2,3,4 but looking at it from the opposite side (of the Rosh) or left to right (for the Shel Yad)
And why do the Sh”R have to be big? Why can’t they be the average size of about 33mm?
