Does anyone know the most efficient log in rate to collect the most turns?

every 18 hrs (quite often reqs waking up in the middle of night and logging in middle of day) or 12 hrs and then 6 hrs and again 12+6 (very often reqs waking up middle of night and middle of day).

you get enuf extra turns to do few extra batchexplores.

uptoyou if you want to sacrifice your sleep cycle to this game.

would every 6 hrs work?

if we are talking about non-express then it wouldn't make difference since you get bonusturns 1st at 12 hrs and then 6 hrs from that and then 12 hrs from that etc.

every 6 hrs you would just make extra sale per day but turns per day would stay same as every 12+6 hrs logins.
