Since we can easily deduce that the 9 levels are given for the 9 digits that make up the first cycle in base 10 numbering before we return to zero (monad) and indicate that by adding a digit for the powers of 10 we might want to ask: why base 10 at all? Why give a story with this 9 and 10 emphasis? What is 90 to you? Is it not a right angle's value in degrees? So we are given a vertical line suggestion for our shaft which is constructed like a ladder that rises from a mystery vault which is associated with 40 in many ways. This is not traditionally a motif that involves weights. It is an old one from when there was an idea floating around about the world emanating from concentric spheres. This, of course, came out of a belief that higher realities were also under the influence of geometric principals where even numbers had female (birthing) qualities. We can represent the money pit visually by showing an overlay of the first unit polygons. That looks like this:

At the core in orange is a Vesica whose number is given by 153 in the geometric esoteric tradition. That, in the OI story, is the depth of the vault in feet.
You should think of the Vesica as containing the mystery of life (2 engendering 1 in birth). If you construct to the 20-gon you will get in the vertical a central ascent of 9 levels (the middle way of Freemasonry). 20 is the number given to death. It encapsulates the mystery of death. To search in life for the origins of the mystery of life and dealt is not going to produce the treasure which is promised to all, allegedly. That treasure is given the number 40, and it stands for the afterlife.
As for weights, we are given 2 000 000 pounds in association to 40 on the stone (omen) with 40 characters if we want to conflate weight with values in pounds sterling. 2 x 1 000 000. Where 2 is female and 1 000 000 is the number given by Dee to Pneumaikos (spiritual insight) in his tree of rarity (Arbor Raritatis). That is in contrast to the branch with the powers of 10 that refer to rationality.
It really is about recognizing the motifs with the OI story, imo. In the tired old story the 7th must die before the treasure is accessed by anyone. The 8th is the Anti-Christ who will be defeated by the upright men. I don't have a clue why this even resonates any more. It's 2 century old Masonic allegory. Rick is doing his best to repackage it for modern consumption.
Hercules carried the weight of the world on his shoulders. When he wanted to go search for the golden apples (symbols of total knowledge) he sat it on the twin pillars (Jachin and Boaz). The pillars are sometimes given as the sides of the ladder in the ascent. The meaning would be that it all rests on the mystery of creation if you are looking for a suggestion to accept.
