Yes it is keeping a record of every request. That is because every request can be different. 
You can change the field of view a tiny bit, tweak the limiting magnitude, etc. Remember we 
don't have "set" sequences and charts now. What we have is a database of comparison and field 
stars with dynamic sequences and fields that change based upon the user's specifications. With 
a unique chart ID, we can recreate the chart and/or sequence that you used. For some more info 
on how we are doing this read these earlier posts to AAVSO-Discussion:
