A lot of the other bots vote after 2,4 hours (2880 blocks), because in theory the voting power should be back at 100% after a 100% vote after 2,4 hours, but in practice if we split a 100% to a lot of posts our voting power is at 97.9%, so it takes some minutes longer to get back to 100%, that's why we vote only every 3000 blocks.
I assume that's the reason of the wrong information on the bottracker page. We will contact the operators of bottracker, maybe they can adapt their software.
