Water draining too fast, but coffee is delicious

Well, I'm using a very coarse grind, this is the way I’m getting the best coffee cup I've ever had with this recipe, my pourovers are even better than the best local coffee shop, which uses a Weber EG-1

But something that's been bothering me is the speed at which the water drains - very fast - it feels like I'm missing something, can I avoid this by changing something other than the grind?
