 > Great. What do we change in these weights then? I still don't see with
 these system-wide weights how we can tell clients to still back off from
 using a Guard-for-a-long-time relay for other path positions, but not back
 off so much from using a Guard-for-just-a-short-time relay for other path
 positions.

 Ugh, I think I have braindamage from juggling too many things. You're
 right, individual relays can't be re-weighted in this way currently. We
 would need client side changes for what I described: we'd need to get the
 duration that each node has had the Guard flag to the client somehow, and
 then the client would have to adjust that node's W*g* weights themselves..

 Either way, it's not something we'd do on the 0.2.4.x timescale. For now,
 we should avoid raising the new limit too far beyond its current value..
