You do realize that it isn’t a percentage per se but rather a relative ratio.
So it’s not that a content creator receives a smaller percentage of a fixed amount of distributed coin but rather that a content creator receives a smaller amount of safecoin for a relatively lower valued resource contribution to the network that is valued at approximately 1:9 subjectively to that of farming. If however the need for this resource goes up relative to farming then so does their allocation of safecoin from the network accordingly.
