Hello @karenmckersie
You do not gain anything voting for yourself. The algoritme take care of it and reduce something it is called the N* factor. I think it is best not to. The best to do so far is vote 20 times a day. The math gave me more on a day when all the votes was for others. Hope the English was understandable.

PS. Have a nice day.
