In dolphin olympics, what everyone wants to do is get to space. Here is one of the ways how:
In the beginning, jump up and out of the water. Then, when you start to fall, let your nose fall in first to do a nice entry. When you get into the water, head back up again, and you should get a little higher this time. Then, as you come back down, again, nose-first for a nice entry. Then, repeat what you did the last two times, and you should get even higher and higher, until you reach space. You can do front flips and back flips while in the air if you want to boost your score. Make sure not to go two far down into the water as that will slow down your momentum. If you can hit any above water extensions, it would help even more. Hope this helped.
I also have a theory if you do a corkscrew while getting a nice entry, you get more momentum. It's hard to prove it though. Sometimes I get more, sometimes I don't
