Multiple cells from Multiple sheets

[Dreamwine59]

I have built a macro to pull data in from multiple sheets to one summary sheet for 8 different areas. It works fine. the way I have it set up is that for every metric, I am in some cases drawing info from 8 different spreadsheets.
then for the next metric I am drawing from the same 8 spreadsheets but different cells. Does it make any difference in terms of processing effieicency to pull all the info from 1 spreadsheet, then go to the next? The Macro is easier to read and modify the way I currently have it, but takes 10 minutes to run 48 cells. I do not have code to open or close the sheets first.
Is there a "correct" way to do this?
thanks
