Hardcoded values should be avoided whenever possible, so I would suggest making this a variable. This would open the door to allowing users to specify the number of records they'd like to see themselves. If you feel like it, you could try implementing that now, although it isn't in the current requirements. Still, if it's not too much work, and would be a good learning opportunity sometimes it's good to go above and beyond the call of duty. I'm just not sure where we'd put that in the UI.
