Importance of the game

Error rate is a function of available time, but it is obviously not linear. Other things complicate this "calculation" as well, stuff like position types, cube availability and so on.
Finally it is very different how much time constraints affect error rates, for each player. I did a poll at the DBgF site last year, asking people how they felt their error rate was affected by speed time constraints, the answers were:
Nothing (add 0 PR): 1 player
Minimal (0-1 PR): 9 players
A little (1-2 PR): 6 players
Considerable (2-3 PR): 6 players
A lot (3+ PR): 4 playersNow, the discussion of match-score vs. game importance is valid, but the most important parameter IMHO is omitted: The cube.
When cube value goes up, so does importance - big time! One should spend more of the available time on games where the cube has a high value, compared to the games where the cube remains unturned. It could be argued - analogue with the points/DMP discussion, that one should then spend more time on all games, since we'll never know when the cube will be turned later, thus raising the importance of the moves made up to that point in that game. However, the probability of a game reaching double and take is not 1, and it's certainly not all games that will see live 4-cubes.
Now, consider Bronstein-time control: It grants you additional time for each decision (commonly known as the delay, even though it is an adder upon move completion, if done correct). But in backgammon, the "move" is either a double/take decision or an actual checker-play. However, a decision "not to double" is not considered an isolated decision, but changed to a roll and checkerplay decision, thus not triggered any additional time in itself.
So, a player with access to the cube (and a relatively close double decision) will need more time, than a player without cube access.
This is why I think one should NOT keep too much time to spare for the Crawford, the post-Crawford and the DMP games. You don't need the additional time as much there as you do with access to the cube.
Decisions where counting/calculations are important are obvious time-consumers, and that's of course the scenario where you could draw an advantage of additional time in DMP, etc. to determine checkerplays based on race lead or deficit.

So Mochy's work is valid, and it should give some thoughts to consider for players with poor time management. But it needs more dimensions to it.
BTW: The discussion of when to spend time vs. the benefit of it and the risk/chance of never reaching important games, must be something you can workout based on a few assumptions (about time/PR impact) and a MET/Match database?
