I can't really tell to what extent you're not computing previous digits (or doing work that could quickly be used to come up with these previous digits) with this algorithm but O(n^2) seems quite heavy compared to
O(1) (I expect) to get the n'th digit of op's number.
Maybe I should rephrase it:
My assumption is: If there is an O(1) algorithm to determine the n-th digit of an irrational number x then the number is still "of a different class" than the likes of pi and there OP might not be able to induce things from this "lesser class of irrational numbers"
Describe the n-th digit of an irrational number without calculating all previous positions of the number.
If pi were a sequence of digits, there is no algorithm to calculate it other than by calculating pi but there is one for op's number. The very fact that he could show the algorithm for creating the sequence of numbers in his post is indicative of that.
For pi such an algorithm doesn't exist (other than calculating pi itself).
I wanted to emphasize this by talking about the "sequence of digits" in my original reply but apparently I failed at explaining this well.

Data scientist/engineer working in a neat and well-paid position is looking for a new challenge, preferably dealing with functional programming and in a quant/trading related domain.
I bring low-ego / social skills, well-rounded technical knowledge and an analytical mind.
A fried of mine reported scientific misconduct (p-hacking) and, together with a few colleagues, left the research group, due to moral harassment by the head of that group.
The university removed all of them from the research group and said they could continue working on the data because it belongs to the university.
3 months later:
- investigations of scientific fraud against the people leaving (neglecting authorship because the data could after all not be used and the head wanted a say in the articles, i.e., change them completely). Also some random other allegations that didn't stick.
- police investigation of defamation (because they reported the scientific misconduct and some other misleading statements used by the head in sales for a research-related product)
- the university now expects them to contact the head of the ex-research group to clarify questions of authorship
