The target is roughly 10 upvotes of 100% per day to have an optimal use of my steem power.
Currently I regularly have free unused upvotes. This means that there are not yet enough JAR tokens in circulation. I will most likely issue another 100 JAR tokens to increase the supply.
The good thing is that people seem to hold the JAR tokens until they really have a worthy post to upvote. So a higher supply should create some more JAR users which can use the token to vote for selected posts without creating problems.
