Maybe. What becomes clear when visiting the archeological sites of Mayans and even predecessors to the Mayans is how absolutely serious they were about the calendar, the seasons, the pathways and timings of the sun and moon, the comings and goings of the animals in accordance with the calendar, etc. I wouldn't call the hypothesis in that paper numerology. It's entirely in line with what they devoted incredible amounts of energy to. Circumstantial, sure, but a bit more than coincidental.
