Amazing lecture as usual, Kol Hakavod! On a sidenote, not all Nusachim have Viduy & Tachanun. I have been saying the Kriat Shema Al Hamita for over 2 years on the Patach Eliyahu siddur and that isn't included. Also, there's no psukim you have to say 3 times, only once. Should be fine right? I'm following the instructions of the book
