For the record, the currently archived (75546 sequences) database 
contains 5 one-termers, 33 two-termers, and 150 three-termers.

Most terms is 232 [A064533], forty more than the nearest rival! Most 
frequent terms is 100 (2615 occurrences), followed in frequency by 
19-termers, 21-termers, 18-termers, 22-termers, and 20-termers. :)

If we had some sort of absolute length-limit per %'s S-T-U, it might be 
possible to determine, a priori, how many terms are enough. But A064533 
implies that length-limits are arbitrary.
