Sir, just to make it more clear... We did NOT cheat any one. The fact as I told you in the firs reply is that bottracker did not update its code to support a new feature of the postpromoter bot code, which we implemented and was merged by @yabapmatt. I will explain better this new feature: our bot gives a minumum 1% of ROI (so, negative ROI free) and a maximum of 10% ROI. So, if at the end of the current round the ROI is above 10% the bot will set a weight vote to fix the ROI in 10%. What happens is that steembotttracker shows the ROI at 100% of vote weight and because of the 10% ROI limit the weight may be less than 100% and this decreases the weight for each post being voted in that round. For instance, in your case, the weight informed by steembottracker is +7.86% and the real weight, is in fact, +5.36%, giving an estimate 10% of ROI. It means that you will get about 10% of return (estimated) after your post is 7 day old. This feature is informed in our steemit page header and also in the post (which the link is also in its header).

Also, as I told you, I have implemented a fix for this bug, and I also asked yabapmat to commit it. But due lack of time he did not commit it yet.

Any way I appologise my self for the confusion we may have done.

Best regards, @brupvoter team
