What is the best strategy for Double or Nothing

[texasman32]

that's if you can keep up a 60% clip through 100 games at a 10% rake.

Not an easy task.
But somedays I win iven more than 60% easy.
But I normaly dont play more than 5 games per day.
Right now I play the 10 double or nothing with a bankroll of 340$ on Stars.
