There is always a computation for the stakes.
Example:
THIS BOUNTY CAMPAIGN WILL BE STAKE-BASEDWhat are stakes?Example: If the total amount of GMD Tokens that will be distributed at the end of the campaign is 45,000 GMD Tokens. This amount will be distributed proportional to the number of stakes the person has gained over the course of the campaign. For instance, if the total number of stakes gained for the signature campaign is 3200 with a bounty pool allocation of 20% and the user has gained 13 stakes. Then he will receive [45,000 * 0.20 * (13/3200)] = 36.5625 GMD Tokens
Overall Bounty Campaign Pool: 1,000,000 GMD Tokens You could try that too from your own campaign.
I think all of them will have the same formula. It will just change when some of the bounty hunter will be disqualified or the ICO changes the amount which will be given because of the amount they got from offering.
