Thanks, jcleef. A vote for you my friend :)
Sorry, I didn't mention that the percentage slider only appers for people with over 400+ something steem. If you have lesser steem, you can't adjust your steem power. Its always a 100% vote in that case.
Every 100% vote drains your voting power by 2% of the Power you have the moment you cast it. Every hour about 0.84% Power regenerates. This means you can 10-11 votes/day and your voting Power would regenerate to 100% the next day.
no need to apologize, this was really helpful and now i have an idea for how long i have to wait to charge and also how many votes i can do a day. You've simplified this a bunch @askaran much appreciated :)
