This is just an empirical result but maybe it can inspire something more
interesting:

the numbers of terms of A007602 with k decimal digits, with k ranging 
from 1 to 14, is 9, 5, 20, 40, 117, 285, 747, 1951, 5229, 13493, 35009, 
91792, 239791, 628412.

Apart from the first terms, the geometric growth seems quite regular.
