Yep, that's what I'm doing this month. For example, my random market cap for this month is 242 and there are 6 five-star stocks out of the list of 30:

				 Mrkt Cap	MF CAPS
CACI International Inc.	CACI	 1,299.16	5
Cisco Systems Inc	CSCO	99,697.50	5
Dolby Laboratories Inc	DLB	 3,524.52	5
Kulicke and Soffa Ind	KLIC	   835.68	5
ManTech Internatl Corp	MANT	   825.15	5
Vaalco Energy Inc	EGY	   421.54	5

So I picked 3 out of these, since I already had the other 3. As an interesting note, of the 30 there were 6 fives, 6 fours, 5 threes, 11 twos, and 2 ones. Pretty evenly distributed!
