Blastenheimer Bullseye

I hit the dead center dozens of time and it never registered. I finally got it after spamming jump when I hit the water. It worked for me and it worked for my friend. I think spamming jump when hitting the water is the key.

Just for future reference, you do NOT need to be on the quest to get this achievement.

Just got this achievement on the PTR when I pointed the camera down and press the button when your toon is over the middle of the boardwalk. Took me a dozen or so attempts to get this one.

Spam jump/spacebar to the center of the ring, seems that wow doesn't register your initial water landing for some reason.

I did this as an orc with 28 home ping and 30 world ping, so if you have a little higher ping, pressing the button slightly earlier may work for you.

Just got this achievement again on live. On my 3rd attempt, I held jump down and when my toon jumped outta the water, he got the achievement.

Edit: It seems that if you have a bigger character model, tauren/night elves, you need to press 1 a little later (towards the water side) than average most since it seems like it tracks where you land feet first. Tauren guildie of mine just got this with a 300 ms home/world ping and pressed 1 more towards the water side of the boardwalk. And conversely, goblins/gnomes/dwarfs may need to press 1 earlier (towards land side).
