Learning outcomes

After this chapter, you should be able to:

  1. Keep the locate step at 55 minutes.
  2. Refuse a guessed saving presented as a measurement.
  3. Leave the protected location as an improvement not yet shown as done.

16.1 The book allowed a hope. It did not record a stopwatch.

Keeping restore instructions and backup credentials in a known protected place could save most of the 55 minutes spent finding them. A classmate writes "saved 40" under that sentence, and another writes "saved 50," each claiming the search is practically gone. The book states no measured saving. Forty and fifty are both outside the file. The locate line remains 55 minutes in the published log. The protected place is one of the three improvements due within thirty days. This lesson does not date that place as finished, and it does not subtract a homemade figure from 55.

16.2 Worked example

Figure Where it would have to come from Decision
55 minutes locating the backup and credentials The published log Keep
"Could save most of that" The book's comment Keep as a comment
Saved 40 Nowhere Refuse
Saved 50 Nowhere Refuse
"The instructions have already been moved." No completion note Leave the improvement open

Synthetic case. Forty and fifty are refused guesses. They are not a second timing.

Errors and limits

Refusing the guesses does not mock the idea of a protected place. It waits for a later exercise to show what that place actually changed.

Worked answers

EX070. Refuse both guesses. The locate line stays 55. No measured saving is in the file. The protected place is not dated as finished.
