Room for Error
Room for error is usually viewed as a conservative behaviour used by those who want to stay away from risk. However, used appropriately it can be the opposite allowing an approach towards risk while still maintaining a comfortable margin.
Being in the right spot at the right time can create opportunities that would otherwise be unavailable. A professional crew will create room for error allowing them to perform to higher levels when the circumstances might otherwise disallow it - for example, always having adequate margins in the size of the helipad LZ enables a late in the day, low light recovery of the crew that would otherwise have been unsafe.
