In a DLG contest situation, there are many tasks where I find myself not throwing with full power. In fact, the only task where I throw with everything I’ve got is Task C – All Up Last Down. Why?

If I throw with all my strength every launch, by the time we reach the fly-offs I will be too tired to throw consistently, resulting in less power (lower height), more wrong release timings (lower height, possibly wrong launch direction), and more hooked launches (lower height, wrong launch direction, damaging to planes). 

The key is to design and maintain a launch technique for yourself where you only use 80% of power, but get 95% of the max height, then you will find going through a long contest much more rewarding, and possibly with increased ranking simply because you have power left and have fewer launching mistakes / mis-timings.
