I like to use https://steemworld.org as it shows current voting power, delegations in and out, account operations and upcoming author and curation rewards. I also try not to get below 80, to be able to start upvoting again the next day at around 90/95%. Takes some math at first to establish a voting patern that works, so your VP doesn't drain too much. We upvote musicians using the tag #ftlob (and other music related content we come across) so it's important to be able to continue to upvote again the next day :-)
Great read and indeed, steem on!
