Yes, your projection is accurate. (1(decimal point)91780821... per day by my math.)

See my above message to set this up properly.

To backup, simply keep a copy of your wallet.dat file in a safe place. Your wallet.dat file can be found on Windows within %APPDATA%\EverGreenCoin\ or otherwise stated, C:\Users\YOUR USERNAME HERE\AppData\Roaming\EverGreenCoin\
On Mac OS X it can be found within /Users/YOUR USERNAME HERE/Library/Application Support/EverGreenCoin/
on Linux it can be found within ~/.evergreencoin/ or otherwise stated, /home/YOUR USERNAME HERE/.evergreencoin/

In the event your current computer becomes none functional, your wallet.dat file could be used on your replacement computer. Storing your private key in a safe location is another way to achieve this safety and has a similar recovery method but, making a copy of the wallet.dat is slightly easier.

I hope that clears it up for you, Porsche911!

p.s. I love your car.
