The ESC card clearly states that ONE calc. token can be used to turn ONE focus result to a crit...if in a swarm where there are multiple calc. tokens within range 1, can MORE THAN ONE focus result be changed to a crit?? I challenged this but my opponent insisted he can. I look forward to hearing back from anyone.

Nope, he was wrong, you were right

No, once per opportunity rule applies. Furthermore, the ship attacking with ESC has to spend its own calc token - it can't use networking for it.

You can use networking to convert focus results to hit as normal, but the effect of ESC for focus > crit is different.

It's worth noting, perhaps, that Networked Calculations only works once per attack/defence, it's an ability of the attacking ship. So, you can spend as many Calcs as YOU have, but only one from an ally, and only one on a crit, only one on a Tac Relay ability, etc.

Thank you for clarifying!
