[Starlink] ookla's latest speedtest app does latency under load

[Brennen Smith]

Hey all,

Here's some details about the final figures:

1. Loaded latency is simply an extension of the latency stage - same
methodology and medium
2. We use a "warmed up" TCP connection for latency
3. We use the interquartile mean for the "displayed value"

Awesome seeing those numbers in the wild and looking forward to bringing
more awareness to this issue.

Cheers,

Brennen Smith VP Technology
