Start moving forward at the moment the water reaches it's lowest point. The first tap happens about the same time as the splash animation that appears as you exit the water. The second tap should be right before you enter the door. This makes it quite a bit easier than the 1 tap method since it gives you more room to grab the spark and a bit of space for running speed through the door to bowling. Use the patch for InfoHUD that shows the dash counter to make sure you have both taps before you hit the door transition.
