Quoted from JoshODBrown:I don't feel that competing against preplays is an equal playing field. If I'm playing against someone who is not present, we should at least be able to see their scores ahead of time, is this not an option? <snipped>
The actual FSPA rules that we are using does cover the pre-play issue effectively, it's just that we've been perhaps too lienent in their enforcement this season as we are trying to make it more convenient for new players and such to ramp up and stay involved.
I do think that we will need to adopt them strictly in the future, the sooner the better AFAIC.

9. Preplays
Preplays allow a player to submit scores in advance for a planned or unplanned absence or tardiness for a league meet. Each player may use a maximum of twelve (12) preplay scores per season.
...At least one other player must participate in a preplay. Before starting each preplay game, the preplayer must announce that the game is a preplay for a specific date, or an undated preplay. For each preplay set, all working games at the league location should be played (since the specific games that will be played by the absent player's group are not known in advance). Preplays are subject to all normal rules of league play (e.g. extra ball restrictions). All preplay scores for the absent player are recorded by the other player and are reported by them to the SLO as soon as possible. It is recommended that the person submitting preplay scores retain a copy of them.
Prior to game selection at each league meet, all submitted preplay scores will be made public. After machines are chosen, preplay scores are recorded on the score sheet.

So couple of key points from that:
Max of 12 preplay scores can be used in a season, so that would mean 3 complete weekly events in one season.
Preplays need to be witnessed by another participant, so you are not playing a single-player game at all but at least a 2-player game. Cheating would require collusion between the two players. Really, there is only so much you can do if someone is that motivated to cheat. This is the one we've been perhaps too lax on, though I know a bunch of people have done it the correct way anyway (with at least 2 players).
As far as the machines themselves playing differently across time, this is also a valid concern but it is difficult to account for realistically. I think the best we can do is enforce the 12 preplay score limit so that any potential advantages provided via the freeplay system are limited by how often you can use it.
