A novel strategy: Always score for your opponents

[StevenB]

I'd like to propose a strategy I haven't seen yet on CD or on the field: always scoring for your opponents. I think it's at least viable, and perhaps even a winning strategy during the qualification matches. Here's my reasoning.

If you lose, only your opponent's score matters (Manual section 9.3.4). Thus, if you're likely to lose a match, you should never try to score for yourself or play defense.
If you think you will win, you'll theoretically get the best score by scoring for your opponents to keep the score near even. But the number of penalties in this game throws a wrench in that plan.
Suppose the other alliance can't do anything. You can score 10 points for yourself, or 10 points for your opponents. Either way, you will get 10 seeding points. However, if you get a penalty, the opposing team will get more seeding points than you do. But if you choose to score for your opponents, you score points you can't lose. As long as you don't get disqualified, any penalties you commit won't affect your seeding score.
The only thing I see that would make this hard is <G29>, which says you can only have one robot in your opponent's zone.
Now, if your opponents figure out what's going on, and start trying to score for you, things could get really interesting. I'm not sure what would happen in this case.

Does my thinking make sense, or do I need to get some sleep?
