Our tests would indicate that one wheel is not enough. Some things to consider are how much compression is needed to impart enough speed to the disc, and how that compression effects the disc and it's trajectory.

I'm questioning why it's necessary to second guess how much each wheel will add, and why it would be necessary to have different wheel speeds for the first and second wheel. What's wrong with running both wheels at full speed. Maybe under ideal conditions, perfectly round and clean and dry disc, full speed is achieved with the first wheel, but maybe under less than ideal conditions the second wheel is needed. Under some circumstances the second wheel is just insurance.
