If you plan to make any changes to a survey, there's an alternative to locking that is usually preferable, because it's more stable, and that is to version out the old question and version in a new question, by date, with the desired settings/point value. It's more stable because a locked shop can be changed to another status at any time, recalculating the score. Also, if changes are made to a survey without versioning the questions, shop views will immediately show any updated question point values, and Chameleon Shop view and dragon shop view widgets that calculate on the fly will display updated scores immediately, regardless of the shop's status or whether it has been recalculated.
