I, too, was constanly staking and delegating my SPT tokens each day, but I got to thinking that I might be missing out on some tokens due to not having any undelegated to earn from my posting/commenting/upvoting. So I continued to stake, but not delegate. I have almost earned (staked) as much as I have delegated. At the point they are equal, I will do a comparison to determine whether I earn more from delegating to @monster-curator or from being active in posts. Once I have this information, I am planning to lean more in the direction of the option that offers the highest return.
