yeah - the amount of sbd gain per % is not linear. It would be good to explain that the return depends on the current voting power.
At 100% => 3x Return - 2 SBD send equals 6 SBD vote value.
At 50% => 1.5x Return - 2 SBD send equals 3 SBD vote value
etc.
If you vote without comment - in stealth mode the max return is x2.
Ok I think I got it, i'll update the site a little later today. Thanks for the info!
