I somehow ended up with desired output and used your way for equation for getting a number a process it in CDEF to get the final line.
$COEF is my final previously calculated number that is close to "24" when you print it, but I still have doubts about that number. How to get "step width" that you mentioned? Playing with numbers I found that "19500" as step width, gives proper line direction, but gives me no clue why 19500. This is rather match question but I would still appreciate your comment on that.
