Duty puzzle scoring

Duty puzzles are scored based on points per move over a period of time.

General
Current best beliefs of most players: Puzzle moves are scored at a maximum of 10 seconds per move. Spending more than 10 seconds to make a move scores a zero. Making moves faster than 10 seconds enters more scores into the scoring frame. This does not mean a higher score; the actual score used to determine your puzzle indicator is the average of the scores in your scoring frame.

The scoring frame is believed to be the last 3 minutes, regardless of the number of moves made in that three minutes.

Efficiency
The concept of efficiency refers to points scored per cost. As an example, if you score 3 points per turn in bilging, at a cost of 3 points per piece played, that is 100% efficiency.

Determination of the "cost per turn" is arbitrary; however, for each of the three basic puzzles it can be set so that 100% efficiency is a well-defined, generally yellow (non-sparkly) or just under yellow indicator.
