But you may not *care* about the actual "current count".
Especially if the modulus of the counter is fixed and
not reloadable.

Usually, the delays are at the input to the first stage
(assuming a single LFSR counter, not a set of counters
of different moduli, cascaded to obtain a specific modulus)
assuming a Fibonacci configuration.

The number of levels of logic (as in number of shift register
stages) can often be rejiggered using a Galois configuration.

Motogorilla (?) had an excellent app note in the 70's on creating
LFSRs of various moduli.  They also see use as pseudo-random number
generators where lengths of 1000 bits are not uncommon (as you
don't want an observer to be able to predict state from any
rational number of observations!)
