Not that I'm not happy with the new payrate, but... will it hurts the campaign budget in terms of duration? I think it'll be very much preferrable as well as showing good reputation for Sinbad across the forum if they can have longer campaign weeks rather than higher [or highest, I think we are the highest right now, no?] weekly payment. i.e., suppose if we reserve to the old payment scheme we can hold it to 100 weeks, and this new scheme made us can only go for 75 weeks, I think, reputation wise, ceteris paribus, the 100 weeks is better.
The final result of the campaign should bring longevity. 75 weeks of promotion should certainly bring enough profit to the campaign owner to continue the other 25 weeks or more. I don't know what the current ROI ratio is for Sinbad.io service, but certainly, at some point, the owner must be in profit, and not just invest his own funds. That is the essence of every business.
