Al,

Although I won't disagree with this approach as I've used it myself, 
I will also tell you that it does have the potential for missing the 
most robust area.  

If for example in using the 25 to 200 by 25 apporach it turns up 100 
as having the best results one would then be tempted to optimize from 
75 to 125 by some smaller increment say 5.  However because of the 
span of the original increment ( 25 ) the most robust area may in 
fact be "hiding" between 53 and 71 which of course gets totally 
missed.  These things become a tradeoff between available computer 
time and other priorities, but I will tell you I do upon occasion set 
up optimizations in the evening knowing that they won't finish until 
the following morning.
