Amount in buffer: 0 bytes
Time spent at 0 bytes: 0%
Amount in buffer at start of loop: 0 bytes, aiming for below 0 bytes.
Overfill target: 0 bytes per interval
Current fill rate: 0 bytes per second, 0 bytes per interval

Total round-trip lag: 0ms
The goal is to minimise the time spent at 0 bytes, minimise the amount in buffer at start of loop, and minimise the total round-trip lag, while maximising the current fill rate.
