Well, you probably know that the F-rating supersede any other instructions, except perhaps "avoid lh/avoid rh".
Once a pitcher reaches F0, he's becoming pretty bad, so I would use the F-rating very carefully. So unless your bullpen is extremely weak, I wouldn't have any confidence with any low F-rating.
Actually, even if you select a high F-rating, say F7, it can lead to danger. Basically, by selecting F7, you tell HAL to not "think" about removing the pitcher before he reaches F7, but this does not mean it will remove the pitcher then, particularly if you have also selected "slow hook" or "conservative use of bullpen". In such settings, it will remove the pitcher only if he gets into trouble, unless the game is a 1-run lead down the 7th or 8th inning, in which case HAL will follow your bullpen instructions.
For my taste, Hal is always too patient with such instructions, particularly considering that I always have at least one good reliever in the bullpen. So the settings I preferred most for my best starting pitchers is to use a high F-rating, say F7 or F6, but set the pitcher on "quick hook". This way, Hal almost automatically removes the pitcher as soon as he reaches the F-state I defined, and does not allow the pitcher to get as much in trouble as with more conservative ratings.
