  For many meta-Fibonacci sequences it is possible to identify a partition of
the sequence into successive intervals (sometimes called blocks) with the
property that the sequence behaves "similarly" in each block. This partition
provides insights into the sequence properties. To date, for any given
sequence, only ad hoc methods have been available to identify this partition.
We apply a new concept - the spot-based generation sequence - to derive a
general methodology for identifying this partition for a large class of
meta-Fibonacci sequences. This class includes the Conolly and Conway sequences
and many of their well-behaved variants, and even some highly chaotic
sequences, such as Hofstadter's famous Q-sequence.
