The presenter seemed to have prepared poorly and his presentation was amateurish. He was nearly incoherent, stumbled on his words, couldn't recall important facts from his prior presentations and seemed to me to be unreliable. I expected to see the camera pan to his boxer shorts and slippers. He was a mess and his presentation provided nothing useful.
For me to take a financial presentation seriously I need to see and hear a presenter who is on top of his game. That's the minimum for me to spend 12 minutes with someone.
I will not follow him on youtube or anywhere else.
If you are interested in how much you can draw on your portfolio there is lots of research by respected industry experts.
5% initial draw with periodic cutbacks of 10% is reasonable. Nobody draws year N money based on the draw from year N-1 plus CPI adjustment and continues this until death. The 4% "rule" is as good a planning idea as many others out there and in fact is really more like a 4.5% rule (according to the author of that research paper).
