That's not really true. The author can get more than 75%. It depends on many factors like the penalty for curators within the first 30 minutes. I might change the description to something like this: Minimum ROI: +1%. Once the 150% ROI promotion period ends, I will change it to 126%. That way the ROI will be gauranteed to be a minimum of +1% and depending on how much curation rewards will go to the author, the ROI can increase up to 10% or even 15% or perhaps even more. And in the meantime, I will change the description to Minimum ROI: +25%.
