Well seen as ginabot pinged me twice in this post, I thought I'd better come take a look!

It's really a case of time/money - however, 'time' can be devoted by someone else as per later in my reply.

You have a 1SP per 1000 SP vested return, which isn't so bad seeing as you are 75% auto.

Manually though, I think you could do much better - 50% better. However, your curation time would also go up. Unless...

For a while, @dontstopmenow was the champion of my weekly league, and that got him a job at the head of a trail in which @cryptoctopus (175k SP prior to him leasing) followed.

Circumstances have changed there recently and so @dontstopmenow is currently available (that may change soon though I guess). Anyway,I think he could get you up to 300SP+ a week.

He was up to around 320SP a week with 175k SP for cryptoctopus, who was suffering at around half that.

I would guess that you could keep some of your trails running, and perhaps lower the vote %, but that could discussed with the man in the know, if you are interested.

Cheers!
