'''
Just to illustrate idea on how I believe the maximum block size should be determined.

My idea stems from a simple scalability metric that affects real users and the desire to use Bitcoin:
Waiting times to get your transactions confirmed on the blockchain. 
Anything past 45mins-1 hour should be unnacceptable.

Initially I wanted to measure the mean time for the transactions in blocks to go from being sent by the user
(initial broadcast into mempools) until the transaction was effectively 
confirmed on the blockchain, say for 2 blocks (acceptable 15~20mins)
