We changed the price around a week ago when I noticed some of the smaller bids were not getting votes due to our Steem Power being so high and steem block chain will "dust" smaller votes (basically ignore them) if they fall under a certain number of rshares.
The PreVote club is very conservative, but still yields significant returns. (I have a case study was going to post about soon).
The way it is setup is it will only drain your account to 90% VP, so you still have most of your voting strength to use on posts you care about and people you want to support. You can easily do 5-6 100% votes daily and still benefit from the PreVote. If you want to vote more than that, no problem, you will only be used to vote once you hit 90%.
There is one scenario we will drain you further which I call Feeding Frenzy mode. If someone makes a bid using our service for a very large amount (think YUUUGE), we will use voters who are below 90% for a 100% vote to get in on the big curation rewards. We will not drain past 80% in Feeding Frenzy mode and doesn't not activate often.
I am planning a "Turbo" club for people who want more aggressive settings but right now I have seen non-voters going from 0.1 SP/week to 2.8 SP/week with only 1000 SP and an active user with 3K SP going from 4.6 SP/week to 7.8 SP/week while still manually voting.
awesome - i very much appreciate your reply
