1. For a considerable period, the oboe players had nothing to do.  Their number should be reduced and their work spread over the whole orchestra, thus avoiding peaks of inactivity.
2. All 12 violins were playing notes. This seems unnecessary duplication of activity, and the staff of this section should be drastically cut.  If a large volume of sound is really required, this could be obtained through the use of a single, much less costly amplifier.
3. Much effort was involved in playing the 16th notes. This seems an excessive refinement, and it is recommended that all notes be rounded up to the nearest eighth note.  Not only would this increase efficiency, but it would then be possible to use paraprofessionals instead of experienced musicians.
4. No useful purpose is served by repeating with horns the passage that has already been handled by the strings. If such redundant passages were eliminated, the concert could be reduced from two hours to 20 minutes with attendant savings in staff wages.
5. This symphony had two movements. If Schubert didn't achieve his musical goals by the end of the first movement, then he should have stopped there.  The second movement is unnecessary and should be cut.
6. In order to avoid such wastefulness in future, it is further suggested that any composer who is writing a symphony should have to get preauthorization, for, say, 12 lines at a time.

In light of the above, one can only conclude that had Schubert given attention to these matters, he probably would have had the time to finish his symphony.
