When someone hits with linked, can you parry twice, and do you suffer 3 or 6 strain.

I read it as you can parry twice, which would be 3 strain each.

You can only parry once per hit, but linked hits 2 (or more) times, so you can parry each hit.

Parry and Reflect are each activated on a per hit basis, so if struck by a Linked 1 weapon (or two hits from a weapon using Autofire), you'd suffer 6 strain from activating the talent twice.

Yes, this can make Linked and Autofire very dangerous to Jedi types as you can force them to burn through strain at an accelerated rate, Autofire especially so as most of the weapons with that quality have a base damage value of at least 10, and many go much higher than that.
