Long range archery

Big thanks to ctc discord users BeliBurkki and Piatato for their test solves and feedback.
Have fun with the puzzle, I'll be happy to read your comments/feedback.
Rules:
-Normal sudoku rules apply.
-Digit in the circle tells you how many steps in the direction of the arrow you have to go (from the tip of the arrow) to find the sum of the digits on the arrow. Moreover, this sum doesn't appear in any other cell in the direction of the arrow.
-Arrows connected to the same circle always have the same sum.
Example:
Digits on the arrow sum to 7 and the circle contains digit 4. Therefore 7 will be exactly 4 steps in the direction of the arrow (the red cell). No other cell in the direction of the arrow (the yellow cells) can now contain the digit 7.
You can solve the puzzle online via:

Solution code: column 5 and row 5 (without a comma or a space)

Fantastic puzzle with some very precise clues!

Beautiful puzzle which stretched my intuition - full of really sharp ideas of unfamiliar kinds. Loved it.

Very fun puzzle!
Neat ruleset with some cool interactions, and not too hard to get your head around (especially by your standards).
The double arrows especially create some cool logic. Very clean solve path.
Not too hard either, at least for me (definitely not 5*).

Awesome puzzle! The multiple arrows/diagonals are a great twist on typical indexing. I overlooked half of one of the arrows for a long time which made this seem much harder than it should've been, but a very clean solve path once I realized :)

Finally, a legitimate reason for the directional nature of this constraint :) I've never understood why it had to be a directed arrow instead of simply a connected line. And also why each arrow goes "away FROM" the total when the digits "sum TO" the total.
Turns out it's to let filuta create this masterpiece :)

This is a masterpiece! Exelent ruleset and very interesting logic. Thank you for creating this. I had a blast! :)

Thank you! For me, the break-in wasn't that hard to find, but after that it took me some time to ask the right questions.
Regarding "suspicious numbers": I saw the digit that had to fit into r4c6 coming for a looong time ... ;-)

Haha, thanks for the comment, seems I'm really getting too predictable.

Certainly an interesting puzzle to solve after Coordinate Arrows! Something just seemed so fitting about it, but at the same time, it tripped me up more than one time because I kept mixing up not two, but three rules (cause reg. arrow too of course), but after I managed to keep everything in check, it went surprisingly well. How you can keep coming with these amazing one-time idea puzzles is just mindblowing!

Thank you so much, happy to see you once again solving one of my puzzles.

Ridiculous puzzle full of never-before-seen logic. Every step is completely fair and completely beautiful, but oh boy it was hard for me to ask the right questions! Finally answering them was a real joy. Now it’s time to re-sculpt my melted brain…

Thank you so much Nordy, hope you had a quick recovery :o)

Took me quite a while to find the break-in, then things went more smoothly - but only because in many instances I had a strong suspicion what the correct sum or distance would be and only had to disprove the alternatives (a method championed by Simon that I'd like to call "profiling", in which the solver tries to slip into the criminally clever mindset of the puzzle creator, in order to anticipate certain configurations of the grid).

thanks a lot for the comment, funnily enough, I must say that, perhaps surprisingly, my goal with this puzzle was actually the exact opposite

Did we just witness a new episode of the arROw SudOkU series ? :P
Excellent puzzle, I quite appreciated its construction and enjoyed its smooth and fair logical path.
............
yeah, I considered it as part of the series, but it just wouldn't fit into it (I see it as puzzles with an unusual use of the standard constraints)

Very nice!

Very cool, unusual ruleset. Good fun!

Cool puzzle with yet another fascinating ruleset. Thanks for coming up with all these great ideas!
