Hello. Just saw your message!
After the HF20, the curation window was reduced to 15 minutes.
Voting at 12 minutes gives me 80% of curation rewards. 20% of rewards will be burned (returned to pool).
According to this vote for 12 minutes is not useless. What did you mean in your message?
Regards, thanks for the reply.
