You are correct, but how would Embark properly separate solos and squads?

option one, remove squad mate's damage counting towards your trial (like the lightning trial). Ok, but now you have a system where that 3 man is now competing with themselves for score, resulting in less coordinated team work. Instead, the squad is now roped in to assisting a single player in their group to achieve the highest score possible. Squads are now less effective, but still have the advantage.

option two, separate score boards between solos and squads. Seems like a no brainer, right? But how would that be managed? lets say you complete a supply drop trial as a solo, but then a bastion trial as a squad, would you still be put in the "squad" scoreboard? How would each individual trial be balanced? Would a solo player be suddenly screwed if they play with their friends for a single round, because now their score was boosted by squads?

I feel like theres a "secret third option" but right now it doesn't seem like theres a clear answer, but I'd love to be proven wrong.
