You would need to include the 25% curation, since 25% goes to curators and the author gets 75%.

I've noticed that during USA work hours 9-5, voting bots are competitive and it's tough to receive positive ROI. I usually like to wait until <10 minutes before bidding on the bot. I look for a bot whose ROI is > 25% with less than 10 minutes to go in the round before bidding. Hope this helps!
