Thanks for the video, I haven't seen it before.
The market I've been dealing with in the past few years appeals to a large community of hobbyists, who have a heavy impact on blogosphere and social media channels. The best products/websites generate a lot of buzz, which manifests itself in a vast amount of nofollow links in forums, blog comments, social media. And I really mean the best sites, they tend to have a lot of nofollow links.
I am not sure 50% is the optimal figure, but 1% is far off for me. 1% means the site does not generate any buzz, nobody is talking about it.
I understand that other niches may be different, but at least in my niche, a backlink profile without nofollow links does not look very healthy. Most likely, belongs to a heavy link buyer, and is not worthwhile community attention.
