Ohhh there is nothing wrong with upvoting your own posts. I upvote most of my posts. If I posted more often, I would upvote them less. Steemocean will show you how much self upvoting you are doing. I just try to keep the upvoting myself below 10%. It is usually at 5 or 6% of my total votes, so even I am guilty of self upvoting a little. You are only at 17.77% self upvote, that is a good amount below 50%. I found that here if you wanted to also be able to see and keep track.
