Dynamic top N rows

[Yuri24]

Hello,

I have a question on selecting top N rows for a data set. I understand I can use TOP N rows from Sample tile to select number of rows I want but what I am looking for is something dynamic. 

Here is the sample data set. Data has been grouped by the field Number and ranked accordingly. However I from each group of unique Number I need to select only half rows. If the number of rows is N and for a group of N is even I need to select First N/2 rows if N is odd then first N/2+1 rows. 

Name	Number	Rank
John	1234567890	1
Jane	1234567890	2
John	1234567890	3
Jane	1234567890	4
John	1234567890	5
Jane	1234567890	6
Shawn	2345678901	1
Shane	2345678901	2
Shawn	2345678901	3
Shane	2345678901	4
Shawn	2345678901	5
Shane	2345678901	6
Shawn	2345678901	7
Shane	2345678901	8
Shawn	2345678901	9

From the sample data set above I will need:

Name	Number	Rank
John	1234567890	1
Jane	1234567890	2
John	1234567890	3
Shawn	2345678901	1
Shane	2345678901	2
Shawn	2345678901	3
Shane	2345678901	4
Shawn	2345678901	5

 Is this possible?

Thanks in advance.
