Balls per inning and APA skill levels

Except if you sucked.. You would have a high number? If you were a runout player you would have a very low number? .... I think there's got to be more to it.
Exactly. If you are a run out player, your innings per game would naturally be lower than if you sucked. If you average 1 or even 2 innings per game, that is a pretty good indication that you are a strong player. (again, you have to account for defense) If you average 5 or 6 innings per game, you aren't close to a run out player, so your handicap should be lower.

You guys all have some decent guesses, however I know exactly what the deal is. I have no interest in generating a bunch of sandbaggers, so I will tell you this:
APA 9 ball SL is pretty much total points made divided by innings (less safes). So if a 4 wins their match in 15 innings with 5 safes (unlikely, but the math is easy), this means that they net 10 innings (15-5). Thus they would have made 31 points in 10 innings, which is 3.1 per inning. This is well above a 4 level score. For what its worth, a SL9 averages just below 5 points per inning (at least). Whatever you think it seems like, this is how the APA does it. I am a 9 and have run 41 balls in a match. Likewise, I've beat a 7 19-1 (total score 75-11) in (after safes) 3 innings. Thus here are some examples of "averaging" WAY more than 5 balls per inning. However, in the grand scheme of things, my overall average is 5.39. By the way, don't forget an inning is one complete turn at the table, not a rack. Thus I could step up and run 3 racks and then miss. That would be 30 points in one inning. Also, notice I'm saying points? Remember that the 9 ball is worth 2 points.
Food for thought.

I'm a horrible SL-9, probably the worst in all of the civilized universe. I very rarely go under 13 innings, and also rarely go above 20 innings. I don't think I"ve hit 20 innings often after safeties are subtracted.
So, that's a BPI average around 4.5 which aligns with what other people are saying.
[edit - just looking at Kerry's last note which reminds me that the 9 is worth 2 points. So BPI is actually a little lower]

The best I can estimate is if you win your game in 20 to 23 innings your skill level is correct. so:
Skill Level & Average points per inning
1 0.61>0.74
2 0.83>1.00
3 1.09>1.32
4 1.35>1.63
5 1.65>2.00
6 2.00>2.42
7 2.39>2.89
8 2.83>3.42
9 3.26>3.95
Obviously there are some gaps & overlaps with this simple formula but it seems to make some sense since all skill levels should reach the points required to win in about the same number of innings.
Remember they use your best 10 out of the last 20 games. Your best games may not be a wins. As a SL 4 playing a SL 4 you could lose 30/31 in 10 innings (3 points per inning) and it would be a "better" game than winning 31/30 in 15 innings (just over 2 points per inning).

I think that each SL is figured on roughly 15 innings a match,,, so
A 9 would average 5 give or take a couple percentage points.
9- 75/15 -- 5
8- 65/15 -- 4.3
7- 55/15 -- 3.66
6- 46/15 -- 3.06
5- 38/15 -- 2.53
4- 31/15 -- 2.07
3- 25/15 -- 1.6
2- 19/15 -- 1.26
1- 14/15 -- .9
Seems right to me and I also heard that 2s and 1s are allowed a couple more innings getting it closer to 18-19.
The highest inning count I can remember for me is 31 and that was pretty rare. Lowest was 3 innings which was rare as well. Many matches under 10 innings and 12-16 common with a couple safes per match.

An inning does not end when the rack is finished, an inning ends when you miss or the match is over.
I say 'does not', however there are things like 'alternating breaks' that screw with this definition.
