You're going to make sure that IPv6 cannot possibly be something you can use by constructing an impractical test scenario that is guaranteed to produce a poor result?

Dual stack, Noel. That means both protocols are running. 

You don't need to nuke IPv4, you just need to prevent Happy Eyeballs from selecting your IPv4 addresses in preference to your higher-latency tunneled IPv6 addresses.

If you had deployed IPv6 on your network, the latencies if the two protocols would be equivalent and you'd be sending and receiving about half of your household traffic over IPv6 just like the rest of us without needing to tweak any Happy Eyeballs settings.

That's up from about 10-15% three years ago. IPv4 is diminishing, and will be at background radiation levels by approximately the date at which AusNOG participants decide to stop blocking new IPv6 deployment.
