This chart fetishism leads to the erosion of critical thinking skills.
Here's an experiment for you with min and max bounds on a prediction. If you set the min and max bounds wide enough then pretty much anything can happen inside. Voila! Instant credibility for your model! But what exactly is it predicting? Nothing. Until you go out on a limb and make a more specific, more linear prediction, you've got nothing.

And the reason Short lost his bet is that prices shot up outside of the (then) wide boundaries that he himself set, something ignored by Baidula.
So the bottom line is...in what way is ETP at all useful for studying oil depletion? It doesn't accurately predict oil prices--that's for sure--not even in a broad sense.
I stopped putting a lot of credence into projections like these after The Oil Drum called peak oil in 2005. The one or two ETP nuts here hearken back to Oil Drum nuts 15 years ago. They just never learned.
The other thing, which was my main beef with PStarr, is establishing cause and effect. There are multiple factors that cause oil prices to be high or low at any point in time. Doomers prefer to ignore anything other than geologic depletion, with classic peakers projecting prices going up with scarcity and ETPers inscrutably predicting them going down.
How this links to the chart fetish is they don't really think about what was going on in the world at each and every time-slice that generated that chart. Everything is explained away as just one thing. But think about what has REALLY happened over the last 10 years or so. The fracking glut (and it really has been a glut), the opening up of the spigots by OPEC to attack the glut. Financial problems in the euro zone. Then COVID. And creeping up slowly behind...the rise of EVs. ETPers or really any peakers clinging to simplistic models don't really look at the details. They are seeking to reduce everything down to an easily digestible "answer" for everything we see. While that's highly satisfying, that's not how the world works, not in the context of day to day or month to month oil pricing.
But anyway, the reason ETP has less credibility than ever is that it has no alternative but to converge the high and low boundaries as the predictive price reaches its termination point at $0. Even though oil prices are likely to be depressed for the foreseeable future thanks to COVID and the long tail of the economic fallout, oil isn't going to just be given away.
