Good question if it can be measured. I looked at my .pal account and not matter how much I write it takes me 8 months to have a dolphin. The Tales & Stories entries/posts I write are never upvoted which make me think why bother and not using and upvotebot @aneukpinenung78 since here is where the Steem went I bought and why should I leave it idle and not earn with it?

If it comes to it growth is about luck and not about writing since I am the person who writes for all accounts and the posts are not equally rewarded.
