I'm working towards the same as I want to get my vote value over the dust threshold.
If my estimate is right, you need around 2000HP-2500HP for your 100% votes to be over the dust threshold. At around 100HP you'll see your vote value tick up to ~0.001.
I could be way off though, I didn't look too much into the relation between HP and vote value.
you are just about right i dont know much about it either I have about 650 hp and depending on how much mana I have my votes vary, mana is drained as u upvote right now I am at 84% mana which reload every 24 hours I think, Long story short my upvote with 650 hp varies from 0.003 to 0.009 and I also noticed that my upvote will put some post up 2 cents if you will while other upvotes boost the post 75 cents or more
Voting Power and Resource Credits both regenerate at a rate of 20% per day.
Also, you might want to check out @dustsweeper, it's quite a useful service.
That sounds about right. I'll be happy getting my vote power to a couple cents then just keep building from there. If everyone had a couple cents for each vote it would add up at an incredible rate as we all started upvoting each others posts. From there it would be a sort of snowball affect and just continue to grow!
