Here are the standard deviations for each type of game (per 100 hands or 100 tournaments). You can introduce these values directly into the Staking EV spreadsheet of the previous post.
|Number of players||Standard Deviation (in buy-ins)|
|Standard Deviations of cash games(in big blinds)|
|Cash NL SH||80|
|Cash NL FR||50|
|Cash FL FR||17|
The Staking EV Spreadsheet has these values there, and you can calculate the standard deviation for a tournament with any number of players.
