Avoiding Collisions?

What is the best practice for sharing the WSPR frequencies? I see that WSPR 2.1 uses randomized timeslots, and suggests a 20% TX/RX ratio. My RaspberryPi program takes a user-specified repeating sequence. The RaspberryPi also can use a randomized frequency offset (+/- 80Hz max).

These seem like good ideas, but what is going to work the best for everyone?
