Dart Game High Score

I've been having a lot of fun playing the festival of heroes dart minigame !
Been grinding it out to try and get enough coins for all the items and things in the shops. While trying out endless mode I managed to get my high score up to 173 before my hand started cramping up too much.
I felt like that was a lot (my aim is really bad) but I'm sure there are people out there with way higher. So does anyone know who and what the highest high score is ?

I'm also really curious about people's performance in general on the minigame / your thoughts, so feel free to post those down here.
