If you change the slider to, say, 40%, it will stay like that during the session until you change it again so that way you can upvote everything at 40%. I upvote photographers at *100% and others usually between 20% and 80% depending on what it is. I upvote comments at 1% just to show some love.
*EDIT: I upvote from a list of photographers at 100% not 40%
Interesting, will have to give this some thought :)
Sorry, made a mistake. I upvote from a list of photographers at 100%, not 40%.
