It looks like you've used over 7 strokes. Every time you roll the dice it's a stroke.
Looking at it, I can only assume your very first roll was a 6 and that the 2 other dice were the same (so your deviation was 0). That's the only way to move in a straight line for 6.
yes I had several perfect shots with 2 dice being the same. But as I read the rules: instead of rolling dice you could do a single stroke. So I asumed rolling dice doesn’t tick off a stroke box. But reading your reply, apparent it does 😅
