Network Weight Calculation

Since the wallet’s estimate of Network Weight is a little under the weather now, here is my calculation for network weight.
If you remember, I take a big staking wallet with a known stable weight and see how many block rewards they win over time. For this calculation a wallet with 1.904 million QTUM won block rewards for 956 of the last 10,000 blocks, or 9.56%. This means:
Big Wallet Weight / Percent Block Rewards = Network Weight
1.904 million / 0.0956 = 19.9 million
This calculation uses an order of magnitude more data points than the wallet's Network Weight, which should be back to its old self tomorrow.
