33.333333333333336+33.666666666666664 = 67
use 1 "/" symbol, 2 " //" is for rounding, sorry.
in Python the // operator stands for floor division, that means it divides the first number by the second number and rounds the result down to the nearest integer.

is just what I wanted to say.

It works for the private key, but what we have is the public key; in this case, Python doesn't round the result.
It's just what the script does (if the condition I wrote is met)

a mathematical curiosity that maybe could help the puzzle:

all numbers even that respects this succession 4,10,16,22,28,34,40,46.....To infinity
divided by 3

plus the sum of +1 to the same number divided by 3, results in an integer, odd number.

Code:
target = 100
target_2 = 100+1 #= 101

t1= target//3  #= 33.333333333333336
t2= target_2//3  #= 33.666666666666664

r= t1+t2 # = 67
---snipp---

t1 = t2 = 33
r will not result in 67 as you said, r=66



33.333333333333336+33.666666666666664 = 67
use 1 "/" symbol, 2 " //" is for rounding, sorry.
even if you run the script it gives you like

pk decimal=67

edit

and if you subtract 100-67= 33
you would get the division of 100/3 rounded to 33.



Unfortunately, this method does not work for all numbers:

target = 150
target_2 = 150+1 #= 151

t1= target/3 #= 50
t2= target_2/3 #= 50.333333333333336

r= t1+t2 # = 100.333333333333336
150 − 100.333333333333336 = 49.666666666666664


Why do you want to apply to a number that is division of 3? 150/3= 50
