I bruteforced a 4-digit 2FA in 2 days, of course with the help of a small script instead of trying it myself. It's always fun to see dumb solutions work.
if it works, it's not a dumb solution :)
If the combination does allow for wiggle room and the 1 in 8000 figure is correct, the code could have been brute forced in a couple hours. Source: my wife has a habit of forgetting the combination to her 3 digit luggage lock and I had to brute force it a few times (it's surprisingly quick, about 15 minutes) :)
The good thing about normal combination locks is that you can try all combinations sequentially with minimum movement. 000 start 001 1 move 002 1 move ... 008 1 move 009 1 move 019 1 move 018 1 move ... 011 1 move 010 1 move 020 1 move 021 1 move ... and so on.
For electronic locks, there is a similar method that allows you to try a 4-digit code for each key press [1].

I feel like saving 1 move in 10 (9 to 10 is 2 moves, 10 to 11 is back to 1 move) is not worth the mental capacity required to remember current up/down direction. Easier to let the muscles do the work and let your mind wonder.

That sounds similar to the concept of Gray code [0]. For electronic locks, there is a similar method that allows you to try a 4-digit code for each key press [1]. [0] https://en.wikipedia.org/wiki/Gray_code [1] http://alvaray.org/brute-forcing-pincode-keypads-using-combi...
Those "try all n in shortest combination" sequences are called De Bruijn sequences in general.

I’m sure the Canadians will be here shortly to correct him.
