Nothing found.. any clues what is going on / what Im doing wrong?
hmm.. it not u.
when I wrote this I wanted to demonstrate that this is generally possible.
Now I see that I did not take into account special cases ...
need to consider and complement
.. manually calculating this is inconvenient, it's time to write a script
python3 script success wrote and add to faq post:

if the checksum(or/and flag compress x01) is corrupted, than recovery now is impossible.
(--stride opt becomes float but must be integer!)
Recovery of these keys is possible only if brichard19 implements support float for --stride opt.
if it is easier to explain..
In WIFbase58privkey, each lost symbol(*/?) to the right is a division stride by 58.
Already from the middle, the stride no longer divides completely.
What does checksum have to do with it? In fact, the checksum forms the float part.
While it is equal, then when subtracting it is reset.
As soon as it becomes different for lowerKey and lowerKey+1, this indicates - stride becomes float.
