Also avoid using ubers in the strategy section as much as possible. Try keeping strategy writing with units easily obtainable for many users. Unless there is no strategy written at all.

Always check your edit changes and how it looked in the "show edit preview" before applying changes. If you are not sure to edit and whether your edit content will be okay, just drop comment in the page and others will do the help if it is fine.
