@sophiamanimen totally no problem...great question.

Once you get to roughly 450 Steem Power, when you go to upvote you will see a slider bar pop up that lets you choose between 1% and 100%. Prior to this, every vote is automatically made at 100%. (We are currently able to make 40 100% votes a day without our vote power percentage falling due to about 1.5% regenerating each hour. This vote power percentage effects how much our upvotes are worth and how much curation reward we can receive on posts. Feel free to ask more on this part if you like.)

The slider bar allows us to break up our 'full votes' into smaller pieces so we can make more of them, for example: I could make 80 50% votes a day without by vote power % falling faster then the regeneration rate. If I cast 80 100% a day, my vote power % would be really low, and I couldn't really add much to the payouts of other authors.

Feel free to ask for any clarification, I didn't want to put to much in there and cause information overload.
