So are you saying as long as a user is able to vote with higher efficiency percentage than the current ROI of a lease, then it is to their benefit to increase their curation earnings by leasing more SP? I wasn't sure if the curation efficiency is the same as ROI.
I hope this example helps.
The voting efficiency is not comparable to the ROI on a lease.
Example: my voting efficiency is 73%.
The amount of SP that will earn me is 458 SP.
That would be 23816SP per year if I can keep that up.
I'm currently voting with a 175k SP stake.
My voting ROI on curating is therefor (23816*100)/175000 = currently 13,6%.
This number is comparable to a lease.
Currently, it makes no sense for me to take on a lease, but it does make sense to lease to anyone offering more than 14% unless I can get better at curating.
