Stack sizes are important yes, when applying ranges and equities with more confidence, so I agree with you in so far as if this was very shallow stack poker. e.g. ~<40BBs that his ranges have some more relevance. But not at ~100BBs and higher.
This is part of what is wrong with his analysis (I'm starting to give some of it away here), that you also have to look at what SPRs will be on the flop given effective starting stack sizes, you can't just blanket say that we have x% of equity against this range if your SPR on the flop is high enough that you will sometimes or often be surrendering your equity by folding the flop. (Sometimes it will be a correct fold and other times not.)
But the above is just one area that he either has wrong in his video, or at least is not covering it in any detail, perhaps he does cover it more in his more detailed tutorials.
The worst part of his analysis though is his ranges that he gives. They are just way out in the real world in so many types and buy ins of PLO games and in many real pre flop spots one can define way narrower ranges than he is giving. This in turn means that his equity calcs he is giving are wrong and therefore his advice on how to play hands is wrong.
Remember, and this applies to NLHE too, the very fashionable current GTO method that a lot of coaches are advocating, including Doug Polk, of basing a big chunk of one's strategy on defining opponent's hand ranges, is not a method that has always been around, used or put forward as the correct way to play.
It is just a theory. Most of the theory is logical but not all of it is practical or works as well as people claim it does. It is really a method, a starting point if you will, to enable or assist in playing a balanced strategy, so to take some of the guesswork out of decision making because by using it, it kind of makes your mind up for you regarding certain decisions.
As far as I can tell, JNandez is a bit of a slave to this hand range based GTO system. It is wrong to be a slave to it in PLO because unlike in NLHE, we have so much more info in front of us we can garner from our opponents betting, bet sizing, and our own holdings, so consequently we often have relatively easily definable equities.
So I get why in NLHE that using ranges mainly makes sense, because NLHE compared to PLO is a game of far less certain information. But in PLO when certain pre flop 3 bet then 4 bet sequences happen from certain table positions, by certain players, with certain effective stack sizes, it is just plain garbage to start running sims against arbitrary ranges as we can define much narrower ranges using common sense fairly obvious logic.
He makes some ridiculous equity assumptions for weak AAxx hands but doesn't mention or possibly even understand that weak AAxx hands can sometimes have only ~12% to 22% in certain spots AIP against certain other pre flop action that is 3 way and are often ~28% to 33% equity AIP 3 way. His analysis is made worse by the fact that we aren't always AIP if we are deepish stacked, whether we are HU or multiway.
This fairly recent new trend of GTO play based on hand ranges could so easily be proven to be a fair bit wrong in some or many areas in 6 months or a year or whenever, but some players and coaches are adamant that it is definitely correct right now. I am not an expert at all at NLHE but in PLO I can see many holes in using hand ranges as a big influence to our decision making, not just in the area of JNandez weak Aces miscalculations and incorrect assumptions but also in other areas of PLO.
Doug Polk hasn't come back to me yet regarding his offer to me to replace JNandez as the resident Upswing PLO coach. I think he was put off by my demand to receive 25% equity in Upwing poker plus free use of his hair stylist once per week.
