This is your voting power. As you can see yours is currently on 61.28%. This happens when you are voting on too many posts. Your vote then hardly counts. You must always try to keep it between 80 - 99%. Never less than 80% and never on 100%.
This you do by voting 10 posts every day at 100% or 20 posts at 50%. You are then spreading your vote evenly.
Good luck!
