I understand that.
The issue is during the bidding round your bot displays min/max ROI as - 20 / None but once the bidding round ends it doesn't give the percentage vote based on what is advertised. The max ROI looks to be around 20 % but I haven't done the math.
In short : Your bot has an upper limit on ROI that isn't displayed.
Perfect and your welcome.
Placing the correct ROI up likely has saved you some future grief.
I will likely continue to use your service from time to time.
It has not been fixed. I was only voter today 18.00 but got 6% of vote. Will make a comment in wallet so everyone can read.
