OK We tried TTLs at 20 minutes for one week. Now for completeness let's try them at 15 minutes.
We already know from SC that at 10 minutes the queries are up very significantly (about 20% compared to 20 or 25 minutes).
At 20 minutes the traffic doesn't seem much different from 25 minutes or only slightly higher, so let's see if traffic goes up much at 15 minute TTLs. If so then 20 minutes is probably optimal. If not, then 15 minutes is probably optimal.

Either way TTL tuning will be done after next week.
