Besides the fact there are some mistakes and things that could have been improved, IMHO i do not agree some comments on this YT link advocating 400 hours are quite few.
Back in the middle 90's, half of my CPL class here on EU vast lands started doing TGL's circuits on the L-1011 on the right hand seat right after finishing it with some 170 hours TT.
All of us succeeded till this very day, except me due disease needed to remain on the ground since 2012 unfortunately.
May she rest in Peace <3
