First, great, thoughtful post. Second, I completely agree and I think that it is a basic game-theory perspective that is supported by your list of four possible outcomes.
Third, I did watch the video (the shot) a few times and asked myself, "If she did call a ball, is that the ball and pocket she would have called?" (basically, could she have seen this coming, if she held to your rule that you must pick one ball and one pocket and call something).
My conclusion: Yes, she should have called this. I believe the two ball was the only ball that was going to be hit hard enough to reach a pocket, and the only pocket that I could see it reaching was the opposite side (where it did go). I don't think the two could transfer enough force to the four to have the four reach a pocket, at the speed she hit the shot.
... [youtube tutorial channel] The problem, in terms of making a living, is that he isn't putting out enough content, and there probably isn't enough content to create on pool tips to engage people daily, or even a few times per week. ...
We've seen a few players try to make the 10,000-hour idea work. At 650 Fargorate, I think this guy is starting farther along. He's currently 647 with robustness 291. I'd say 720 within a year is the minimum if he's going to make a living mostly by playing.
I saw this a few days ago and commented. I wish him luck and all... but 650s are not uncommon, and very few make into the ranks of guys making a living as professional pool players unless their time at 650 was "just passing through" on their way up.
Regardless, I wanted to address the idea of him making an income as a YouTuber (because I do know a bit about this stuff). I have a friend that makes his living as a YouTuber (about $10k to $14k a month). He has nearly 250,000 subscribers* and his average video is watched about 80,000 times. He puts out a video almost every day to reach that income level.
It looks like this guy tried to be a YouTuber in the "pool tips" space for nearly seven years, accumulating 40,000 subscribers and his videos are watched an average of about 85,800 times each. There is a huge variance between his watched videos (over 200,000 views for several, and a few over 700,000) and the run of the mill videos with only a few thousand. So, he does have a monetized channel that makes some money. The problem, in terms of making a living, is that he isn't putting out enough content, and there probably isn't enough content to create on pool tips to engage people daily, or even a few times per week.
We'll see where it goes, both in terms of his playing level and the number of views he gets and the frequency of videos posted.
*Subscribers does not lead directly to payment. Your pay comes from views. However, the more subscribers you have, the more people your content is pushed to and they are more likely to watch video after video. So, subscribers and views can run hand in hand.
For me, Strawberry Brooks is right up there, but perhaps it’s because I spent a lot of time around him. At the very least he was better than anybody with a cigarette hanging from his mouth while playing
