Hope it Helps.
Yes, i don't know also. What got me thinking was when i first saw your feed and opened software update. The first thing i noted was the different sizes in the download, went and got my wife's MB, 180 like yours. I have a 1st Gen MBP btw.
Good point. It seems very random how the sizes are assigned. I know two people with identical systems that had a 200 MB difference in update size. Can't explain why.
