Your pending vote value is tracked in rshares (shown in the second bullet point in the status response). This grows at a steady rate, based on your subscription level.
When you upvote our posts/comments, your upvotes increase your pending value by 1.34 * value of your upvote. So if you upvote the post by $0.01, your pending value will increase by $0.0134 when that post pays out.
Each time you post, you will get an upvote of 20% of your pending value, as long as your total pending value is high enough for that to exceed the minimum upvote amount of ~ $0.011.
