common for someone to want to "sleep it on it" before making a
decision where the decision is important but it is not clear what
decision is best. If a decision is essentially predetermined then what
is the point of that time and effort or sleeping on it?

Do you not see that this argument depends on the belief that there was
an *option* to make the decision earlier under different conditions
(lack of 'thinking it over' and/or 'sleeping on it'). IOW that free will
exists. You are 'begging the question'.

It's actually the complete opposite, I am starting with the assumption
that there is no free will and asking what then is the point in
deliberating over the various options. You seem to be taking things a
bit further and saying that if determinism exists then there aren't
any options to begin with but that is just a variation in emphasis, it
doesn't address the question of why we spend so much time pondering
those options when they don't even exist.

Consider writing an algorithm controlling a robot walking down a path.
The robot comes to a fork in the road. Does it take the left fork or
the right fork?

The algorithm can have layered complexity. Scan left, scan right,
process data. Simple-minded algorithm scans 1 sec each way, sums up
some score of positive and negatives and picks the best. If it's a
tie, it might kick the random number generator into gear.

Alternatively, it can get into a loop where it keeps scanning left
and right until one "choice" passes a threshold for "better" that
is not just a greater than sign, maybe 10% better or such. From
the outside, this is "pause to think". With a little imagination,
one can add much more complexity and sophistication into how the
robot chooses. It can be dynamically adjusting the thresholds. It
can use it's wifi connection to seek external data. It can find that
its wifi signal is poor at the fork in the road so back up to where
it was better.

Map "go home and sleep on it" to some of that or to variants.
Map it into Don's words. The robot could not "choose" left or
right until its algorithm met the decision threshold, i.e. it
didn't have a legitimate option yet. (hopefully he'll correct
me if I have abused his intent too far)

To an outside observer lacking full knowledge of the algorithm,
it looked like it had a choice but inexplicably hesitated.

 It is *you* who have missed the point. What you have described above
is an algorithm to process data and arrive at a decision; what I was
asking about is why we delay once all the information that is
available or likely to be available *has been processed*.

How do you know that that actually happens? In the 'free will' situation why does a delay happen? And how does any explanation you give distinguish from a deterministic situation?
  Once all the

information has been input in your algorithm there is no reason for
the processor to continue analysing unless you add in some sort of
rather pointless "just hang about for a while" function;

Dagget's robot description makes the "just hang about for a while" function eminently pointed.
  no matter how

many times your algorithm runs with a given set of inputs, it will
reach the same decision. One exception to that is your suggestion of a
random number generator when the two options look more or less equal
but your problem is that that randomness is very antithesis of
determinism.

As I understand it, the 'hidden variables' idea in physics is pretty much defunct, so there is some randomness built in to the universe. T his effects my idea of determinism to make it only predictable probablistically. Highly accurate in the short term but poor in the long term. How does the 'free will' idea handle it (randomness)?

 In that case, it would have been useful for you to retort to the
example I gave about my wife in the second half of my post which you
ignored.

An added thing to consider is where "consciousness" comes into play.
All the data the robot is scanning can be processed by sub-processors
that generate most of the information needed to produce a choice
before the central processing algorithm distributes instructions
to the subroutines that activate whatever it is the robot needs
to do to locomote down a path. Fill in the blanks.
