We can try to mitigate this phenomenon by giving higher priority to young guards to be picked as guards:
I'm pretty sure this section has it backwards from what was the intent of the discussion of "guard age" at the dev meeting.
Right.
The weight factor should be applied when choosing a "new guard" as a middle or exit node, because it is being underutilized as a guard. This makes it straightforward to apply: if relay R has had the guard flag for fraction k of the last rotation period, then its weight for some other position should be
k*(weight with the guard flag) + (1-k)*(weight without the guard flag)
Sounds good to me.
