Sounds great.

I would be interested in learning the results of those simulations!

In any case, starting the tor implementation will be useful anyhow.  Even if
the very final algorithm is not 100% the same as the new prop259, it will
definitely be closer to that than the old mess.

Maybe we can have another IRC meetup this week to speak about the simulation
results and discuss how the little-t-tor changes could work? I will be
available tomorrow and on Wednesday from 14:00 to 18:00 UTC. Let me know if
that works for you.
