Hi @allenaxie,
That is a very good idea, you should keep your power above 80% to have maximum effect on people you really want to reward. I know there is so many but we must prioritise. :)

A good rule of thumb to cast 20 votes in 24 hours so your power will always stays above 80%

You can slow down of course there is nothing wrong with that and now it is the only thing you can do to get back in "shape" ;)
