Interesting points.
I'll throw out a rough hypothetical then based on the current numbers this morning.
441,000 (Total supply today incl. burned) * 7.5 = 3,307,500
Current burn percentage = 0.25%
0.25% of 3,307,500 = 8268.75
As I mentioned in the post, I'm no mathematician. Can you see any other contributing factors which would decrease or increase the burn percentage from its current percentage of 0.25%?
