^Because you need to pass over certain spots to get the lap to count. I believe there's a vid on youtube that gives a decent explanation, I'll see if I can find it for you.

ty the explanation and the video helped me a lot

Sadly, yes, that is mostly by practice =/ The best way to get good at it is to copy what Alex, Niyake, or myself do via the ghost (or Clements if you have it but his strat is different). This is a place where racing against one of those ghosts is greatly helpful for getting up there. Once you have the positioning down, the timing of the Mushroom is also key. Use it too early and you fall short, use it too late and you'll be behind.

To this day, I still like my ghost the best though b/c of my superb 1st lap, 8.689. Being able to see where the ghost goes so you can repeat the lucky bounce is incredibly helpful....sadly, I'm not 1st reg or ww anymore so my ghost isn't available except via Rival Ghost if you're lucky   (or if I send it to someone).

For getting on the rock, follow Alex, Niyake, mine, or Sasuke's ghost if you have it. Personally, I like the way Alex/Niyake/I do it best as Sasuke's method is annoying if you ask me.

Once on the rock, after you pass the finish line/checkpoint 1, move in tight but be careful not to clip the right side of the rock (which would be on your left). When going around the rock towards checkpoint 2, go outside through checkpoint 2 and then try to get down the middle of the "road" after crossing the checkpoint. After that, go up the right side of the hump so as to cross the finish line/checkpoint 1 (you'll know what I mean when you see it).

Rinse and repeat via lap 2 and continue that into lap 3. For the final 2 shrooms, just follow the last part of the flap strat which can be found here, http://www.youtube.com/watch?v=7fe8mujD9CQ&fmt=18 @ 0:31.  Use the Mushroom a bit earlier though but still in the air.

Go at top speed the whole way except for crossing checkpoint 2 and crossing checkpoint 1 when going from lap 1 to lap 2 and lap 2 to lap 3. If you need to slow down, release A only for a split second and then press it again (line yourself up during this split second). If that isn't enough, then resort to pressing B.

You own Jaws! Get that sub 20!  

about tightness, the turns that have a "hill" can be done easier pushing up too (like a nosedive in the air). I dont know if you do that, and as for getting those splits: consistency

where do you crash the most?

My 2'33.749 time was on WW Top 10, same w/ my 2'33.717 time, right now I'm not on it and probably won't return cause TT's are a snoozefest to me now.

It depends of the first lap, iirc if you hit lap 1 splits lower than 24"250, then you can switch to the WR strat. My PR (1'14"5xx) is 1-2-0.

Indeed. I did my 1:14.733 with 1-0-2 with a 24.3x first lap I believe.
