How many teams do you really think will be able to autonomously distinguish the start of match center goal positioning correctly with I/R signal detection, and accomplish one of three (or six, depending on start point - ramp or floor) driving paths to reach an accurate enough relative position to the center goal, from which they can consistently score one ball in it?
No way half the teams will do this, not until maybe even the level of competition at World. So, I knock off 30 autonomous points for your max. scoring projection for early in the season finals match competitions, 15 points for later in the season finals, and 6 points for World's finals.
So IMO, an alliance scoring above 200 in autonomous will be extremely rare in early qualifying competitions, very rare in state competitions, rare in super-regionals, and infrequent in world competions

My 50% assessment for the center goal was capable not successful. I'm guessing there will be a significant percentage of robots that are not designed to lift (or shoot) a ball 120cm off the floor. I agree that in early tournaments we may only see a 10% success rate. Every robot that's capable of lifting a ball 120+ cm should be "capable" of dropping it in the center goal. The success rate should go up quickly!
Consider a brute force strategy. Line up your robot on the mat in the center of your protected starting zone, against the perimeter wall, assuming that you will get starting configuration #3. At the start of Autonomous, drive straight forward until you engage the center structure. (Simple guides, not grasping) Raise your ball 120+ cm and drop it in. In theory, this is a 33% strategy. Even planning for mishaps, it should net 25% success.
Touch, EOPD, or Ultra Sonic sensors could easily be used to determine if you are correctly positioned. This should increase the success rate.
Now more clever teams will use that IR Beacon to help determine if they were right in their guess. If they sense that its not in position #3, they can make a decision to hold on to their ball or make a move to position #2. Then position #1.
In truth, you can do this without ever using the IR Sensor. You can do all this with just the position sensing.
This strategy should be accessible to any average or better team. Considering this is worth over 100 points, its well worth the effort. (60 points in Autonomous "plus", another 42 points in Endgame, assuming you use the large ball)
