Yes, it is, a total of 72 times, counting the ones the Priest makes over objects such as incense and the gifts.
The Signs are made as follows (according to the 1962 missal):
*The beginning of Mass (as in the OF)
*The end of the reading of Psalm 42
*After the peoples Confiteor
*At the end of the Munda cor Meum
*The beginning of the Gospel (as in the OF)
*The end of the Creed
*Three times during the Offertory
*At the beginning of the Last Gospel
*At the Dismissal (as in the OF)
So, that is a total of 11 times by the Faithful, compared to 2 in the OF.
The times the people (or servers) make the sign of the cross in the Traditional Mass are:
[presuming that the elements like the Gloria, Creed, blessing, etc. are included in that Mass, and that the people always follow the server, which may not happen at places like the Introit]
Beginning of Mass
Adiutorium nostrum, at the end of Psalm 42
During the Indulgentiam
At the beginning of the Introit
At the end of the Gloria
At the beginning of the Gospel
At the end of the Creed
At the Benedictus qui venit
At the blessing
At the Last Gospel
By pious custom, people may cross themselves before/after receiving Holy Communion (although servers should not do so).
The people should not sign themselves at the Munda cor meum as that pertains directly to the ordained minister; likewise at the Offertory, they should not sign themselves as those crosses are directed toward the bread and wine (and incense)
The biggest difference is at a Requiem Mass, where the signs of the cross are as follows.
Beginning of Mass
Adiutorium nostrum
During the Indulgentiam
At the beginning of the Gospel
At the Benedictus qui venit
At the Last Gospel (if there is no absolution over the catafalque, in which case the Last Gospel is omitted)
