What happens if you have: 
   group1 10 20
   group1 18 22
   group1 25 21

[download]
When looking at the first numbers, 10 and 18 are less than 10 apart, 18 and 25 are less than 10 apart, but 10 and 25 aren't. Do you want to keep the 10 (because it's the lesser of 10 and 18). Do you want to keep the 18? (because it's the lesser of 18 and 25). Keep them both? Is the 25 discarded? And if I have 
    group1 10 20
    group1 15 25

[download]
What is the result? 
    group1 10 25

[download]
that is, take the lesser of (10, 15) and the greater of (20, 25)?

Finally, what if I have: 

    group1 10 15
    group1 15 50

[download]
The first numeral values are less than 10 apart, so you keep the 10. But 15 and 50 are more than 10 apart. What's the result?
