Hi there. I created simple page where users can check sum of bids that @boomerang received so that you dont' have to manually check the wallet. You can find it at http://vetercek.com/steem/index.php. I also wrote short blog post about it at https://steemit.com/steemit/@jaka87/boomerang-bot-roi-tool. I hope users will like it and find it usefull.
