True - but extra repetitions do not count as disturbing duals. Many endgame studies have optional repetitions for white which do not affect the outcome or the judgement of the study.

This is not an endgame study. it's a game played by me and my dad. (I won.) It is the only position that I remember playing against my dad.

All puzzles of the type "black/white" wins/draws are considered endgame studies in composition country. If the instruction is "checkmate in 5 moves" it is called a "direct mate problem".

I bet you changed the game position a bit to make it work as a puzzle. The knight on d2 is very strategically placed to prevent alternate solutions. Which is OK because exact game positions are hardly ever good puzzles. Whatever is the case, the status of the optional repetition is the same. Repetitions do not hurt a puzzle solution while duals (different solutions) make it almost valueless.

Yes, I did. The knight was originally on F3
