There is actually a 4th related draft which is a new Q algorithm:

We are working towards this, part of the problem is the tools
and the data was evolving at a pace faster than we could publish them.

We have now validated that an independent person can build,
install and run a SCE capable linux kernel avaliable at:

	https://github.com/chromi/sce

Note that this is evolving code, so expect to see updates,
as well as complete notes on new sysctl's avaliable to
enable/disable features for testing purposes.
