Yes, and that is reflected by your contribution value in those games.
Going 10-1 is better than going 30-22 and 20-12 -- but not better than going 30-20.
Contribution average is a simple formula:
Kills - deaths / games played.
However, camping is frowned upon for good reason, even though it definitely is the most effective strategy -- unless the other team also uses it. Which is the problem, as discussed in the other threads:
It's a prisoner's dilemma.
But I can go 30+ and >5. That's +25 vs. +10. And the funny thing is, I have done that and told the opposing team in advance where I would be and what I would be doing, my entire loadout, and where I would plant claymores/IEDs.
You're too focused on both teams using the strategy when, in fact, that simply does not happen in multi-player. But I'll address that in the other thread. Let's stay in one thread. Camping threads is not frowned upon.
circular logic plug:
It is absolutely impossible for everyone to have a good KD (of course we need to define what good is). That would be like saying every basketball team in the league can be the champion. We must remember, for someone to win, someone has to lose.
