PG scoring rating on the away team is 98.6. It means on average his PGs should score 99 points on 100 shots. The PGs in that game combined for...6 points on 17 shots. Now since you are so fond of averages and you don't have to be a stat genius, or any kind of genius to understand this, that rating means that if they play this exact same game again th PG could score 47 points on 17 shots. Simple napkin math is your friend here.
That's not how statistic works, another important fact is that the past does not influence the future. If you flip a coin and it's tails, doesn't mean the next time it has to be heads or even have a higher chance because it needs to average out. You still have 50% chance to get heads, regardsless of what previous results are. So no, the PG's don't have to score 47 on 17 shots for the scoring rating to be true. Besides that, I don't you can adjust PP100 that way because of actual limitations on Points per shot. The ratings just say that if those PG's would play a statistically relevant number of games, say 1000, on average over all those games they'd score 98.6 PP100.
What would you want those ratings to display then? The actual PP100 of that game? What use is that, you can just calculate that yourself and it doesn't give you more information. The information you can gather from this is that on average the PG's should score 98.6 PP100, and because they only scored 6p on 17 you can conclude they had a bad offensive game, an outlying result. Since the PP100 is a decent number, you don't need to change anything. Now if the PP100 was much lower, you can conclude the performance of the PG's is bad because appearantly they are bad offensively, so you could try and change that.
If you don't think it's logical that a player that scores 98.6 PP100 on average has 1 game in which he scores 6p on 17, that's just how it is, good players can have bad games. Lebron James normally has a great PP100 but he has games in which he shoots badly too. Now if that player has 10 games in a row in which he shoots as bad as 6p on 17, then you can ask yourself what's wrong, because that is a much smaller chance than 1 guy having a bad shooting night.
Look I don't want to sound like a smartypants, so sorry for that, I genuinely want to explain basic statistics to you if you like. Just tell me what you don't understand and I'll try to elaborate.
