I like the $50,000 / epoch allocation to the Darknode Community Fund.
I think as long as $50,000 is less than 10% of the overall fees collected it should be the standard amount allocation to the Darknode Community Fund each epoch.
Once $50,000 is broken, I think moving to a 10% allocation to the Darknode Community Fund is fair. This means that each epoch the Darknode Community Fund would be allocated 10% of the overall fees collected.
