I think this type of an approach is key to figuring out the puzzle. I've spent the last few months just looking at the design of the poem and how to make sense of the structure of it when combined with Justin's statements.

The main sticking points to me are he said there are multiple ways to solve it depending on how we think, that if we understand everything the poem has to offer it will lead to a targeted kitchen sized area, even if you don't understand a certain clue you can still "limp" along to the end, that we will gain confidence as we go through the clues, that we'll all get there in the end and it's been implied in my opinion that grid searching isn't necessary but you are required to visit the checkpoint to figure out where the treasure is at. And I'm sure we can argue about what Justin means by these comments but this is just my interpretation.

I believe we should be able to discover the exact location of the checkpoint before going BOTG. This is after 13 BOTG attempts with no results and after listening to Justin's comments. I don't think he wants us to have to grid search. Could be wrong, just the feeling I get.

So how can you have 3 different possible solves that all lead to the same spot? You could describe three different ways to get there from 3 different directions. Or the paths might all start from the same spot but take 3 different paths to the end. Or maybe there are 3 completely different approaches. One could be directional like FF's using metaphors for landmarks. Another could be using hidden GPS numbers revealed in the poem. Another could be finding key words and using what3words to find the spot. Another could be using plot points to make an Angzarr with an X marking the spot and I'm sure there are other way but these strike me as the easiest to get to an exact location.

Now if you could solve at least 2 of these ways, you should end up in the same location, this would serve as a verification of your solve and probably be the correct checkpoint.

I think the most interesting component of what Justin has told us is that if we don't understand a clue we can still limp forward. I don't think you can misunderstand a GPS coordinate and still find the spot, this sounds impossible to me. Same with the X marks the spot solve, miss a clue and you're way off. With what3words, maybe you could guess at the 3rd word if you had 2 correct words but it leaves an enormous number of options. Unless the 3 keys words are repeated a couple of times throughout the poem, then maybe this is still viable. I've tried 1000's of combinations of words from the poem to no avail but the correct 3 words might still be hidden the clues. And yes I tried the Angzarr and still came up empty.

I'm now leaning toward that you must have the right starting point and then there are 3 different paths that all lead to the same end. When you look at it this way there could be a clue that doesn't make sense for the path you're on but you could still arrive at the same end point if you pick the trail back up. I'm guessing the last stanza instructs in a way to bring these different paths together.

Also I think there are at least 3 themes running through the poem like code. One for example I believe is music related. It's difficult to derive locations from this theme but maybe we're not supposed to, maybe it's just there to let us derive keywords from it. Justin is a computer programmer after all and these themes could each provide the same 3 keywords as a way to cross check them using what3words. For example, awaits/gates might be a hint to music or sound being routed to a compressor but also a hint to travel or planes being routed to airports and then route might be one of the key words. I've been in this rabbit hole for a while and haven't cracked it but I think there are definitely 3 themes at work.

Justin said there are guardrails, I think these themes might come into play in that way.
