At 25:50 he transitioned to the CL charts. Up until that point he had ES on Bookmap and ES on SC.
Then he transitioned to CL in the context of news. Then he went back and forth between the two.
If you want to show a different aspect of how you analyze Bookmap, I would be more than happy to have an interview with you. Not being sarcastic.
I like Tom, and I rarely see someone who has methodical as him when it comes to software.
His knowledge extends beyond what he has just shown, and although I can not talk performance due to privacy policies we are bound by, he had no motive but to share his knowledge.
I respect your analysis and your opposite view.

Yes, he does go back and forth between CL and ES, but at 32:50 he makes the direct comparison. He talks about how a huge order is gone when comparing the current order on the DOM in Sierra vs. the historical offers on Bookmap, but this is because he is on two different instruments. Like I say though, its just a slip up.

I don't use Bookmap as Sierra now implements the same idea quite well.
But here is just a random sample as I looked through my charts to show some nice variances and why its difficult to just trade with this info.
1. Here we see an ASK level that just slightly sticks on. On first encounter, it makes price bounce off nicely. Then it pulls even before its hit and price goes higher.
2. Here is an even thicker ASK level, and it has no problem trading and going higher. (although granted, not by much)
3. Here we see a thick BID that pulled as price comes down. So now we have to wonder, did buyers disappear and it will go lower or not?
4. Here is a thicker ASK, and yes, it pushed prices down. (or note is that its across several price levels and not just one)
5. Here is a very thick BID, it trades, but price goes higher, so nice support.
6. Here it trades again, and another bounce. But as you can see, on the third try, it breaks no problem, and eventually ends up lower.
So although its nice to look at, and it almost looks like there is an edge here, there are several combinations that we have to be aware of.
As price approaches a thick level, it can either bounce off, or it can trade through. The resting orders can also pull, and now you have to wonder if this means the buyers or sellers disappeared and what affect this will have on the direction. Yet another variation is when a thick level appears just above or below price as it is moving (ie. more people wanted to get on board, and some call this backfilling). So its not so much a resting order, but a new one that was just placed in this case.
Furthermore, these levels are usually 500-1000 contracts thick. (ES used to be "thicker" years ago) This amount of volume can trade in seconds without any thick levels to be seen. So none of these resting orders really have much of an impact. If you want to load up on 1000 contracts, you really don't need to show this size and can easily accumulate it over just a few seconds.
Now of course if it was all just trickery, traders would learn its fake and always fade it. So it has to "work" half the time, and fail the other half, to keep everyone guessing. But now you're guessing which time it works and which time it doesn't.
I know that Bookmap also shows visually what's traded at each level, but this too isn't the smocking gun. Just because there is a huge order at a level on the BID doesn't mean its gonna support price and it will go up. On days when price is falling, there are often huge BIDs that get hit, and price keeps dropping. The fact that someone wants to keep buying on the way down doesn't mean that they are supporting price and trying to make it turn around.
Anyway, these are just a few of my random thoughts. Sorry to be so critical, and I'm sure Tom knows quite a bit as well given that he has been doing this for so long, but when I watched the video, I felt bad for an amateur that would get the wrong idea.
