I actually liked the video and it is not because Leo recently became a member of this forum (
https://www.pizzamaking.com/forum/index.php?topic=61317.msg611877#msg611877). I liked the video because Leo was so thorough in his instruction as how to make the dough. And judging from the comments section of the video, it looks like others liked the video for the same reason that I did.
As for the 00 flour, Leo did say that a higher gluten flour (around 14% protein) could also be a suitable flour. Also, Leo added about 11% fine semolina flour to the 00 flour, which would make the dough stronger and require a hydration value a bit above the rated absorption value of the 00 flour. Some years ago, when I was attempting to reverse engineer and clone a dough made by Papa Gino's in the northeast, and whose pizza was often likened to a NY style, I also used semolina flour (a coarser version than what Leo uses), together with a bread flour. As it turned out, I learned that PG did not in fact use semolina flour. But I learned from my experiments, and I nonetheless enjoyed the pizzas using the semolina flour. I summarized what I achieved at Reply 115 at:

Based on Leo's numbers, I calculated a hydration of 60% for his flour blend. That was a bit less than what I used. But, like Leo, I did not use any oil in the dough.
I should also add that another member, Evelyne Slomon, who last visited the forum last year, once posted a recipe for a NY style pizza using 00 flour. The recipe is given at Reply 606, at:
https://www.pizzamaking.com/forum/index.php?topic=576.msg41054#msg41054Like Leo, Evelyne used 1% IDY (Leo uses a 7 gram packet for a flour/semolina blend of 750 grams) and a hydration of 60%. However, she added a fair amount of oil and somewhat less salt (Leo uses 2.8%). She also contemplated the possibility of making an emergency type dough, which makes sense when using about 1% IDY.
