Comment (by arma):

 I'm afraid I'm a bit late to the party here, but: we should consider that
 the CircuitIdleTimeout config option was chosen with this 1 hour period in
 mind. If you set your PredictedCircsRelevanceTime but leave
 CircuitIdleTimeout at 1 hour, you're going to build and throw away 24
 circuits (give or take a fencepost). That's not very nice to the network.

 Whereas if you raise CircuitIdleTimeout to go along with it, then a) you
 soak up more resources on relays even when you haven't used your Tor
 lately, and b) you stand out more to the relays as somebody who fiddled
 with her parameters here.

 I'm not sure what to recommend. My first thought is to not let
 PredictedCircsRelevanceTime get anywhere near 24 hours.

 What was the original use case again?
