The main discussion for the weekly clan Naval Battles is over in the other thread, https://forums.oldtimersguild.com/t/clan-battles/13950
I’m not sure what you’re asking, what are your concerns? We’ve been more active lately, and until the matchmaker catches on and puts us in harder matches, we’ve had the high score lately. 
The key, as I see it, since each person only has 10 attempts available to them, is to grab the initial easy stars in the categories, then have those who are more proficient, and have high tier ships, work on the resulting higher threshold stars.
When there were three of us mainly doing the Naval Battles, I’d try to grab what I comfortably could on Friday, as the novice with a limited roster of lower tiered ships, then @thesuperles and AngelsOmega would come along later and grab the higher threshold stars, as well as categories that they had ships for where I did not, such as aircraft carriers. I’d return on Sunday and blow my remaining attempts on stars that might be within my reach that were remaining.
From my understanding, the criteria for the thresholds rotates every two weeks between “base XP”, “ribbons”, and “damage”. Random Battles may be the best approach for “base XP”, Co-op battles for “ribbons”, and “damage”?
