It should be explained to you from the very beginning as you learn the motions so you know how abstract training relates to fighting strategy.
---I'd say that if you can't explain to us how the simple motions from the Saam Bai Fut section of SNT apply to your fighting strategy while having nothing to do with the position the elbow follows along the elbow line, then your system is likely is a bit too "abstract" to be all that practical.
It could equally sound like I train it for longer than an hour. I often train outdoors in the evening and don't wear a watch when I train, so I don't know.
--Well, I will give you guys credit for one thing.....at least you neither one out-right lied to us and declared "of course I spend up to an hour doing the Saam Bai Fut motions on a regular basis!"
But you are leaping to the answer you want me to give so you can proclaim that training this way is only legendary and nobody does it, because you have no other explanation for it within the fight training methodology of Yip Man's VT and can only assume it's for Buddhist meditation, even though the guy was not a Buddhist.
---And now you are putting words in my mouth after I have already explained here what I meant. Recall I noted that you don't have to be a Buddhist to practice basic mindfulness meditation. I never said Ip Man was Buddhist. I also pointed out that I learned this basic aspect of the SNT form when I first started learning Wing Chun 30 years ago. I didn't make it up.
