If it's against the first attack against you in a round, that's against -all- the attacks against you in that round. Unless your enemies have awesome time travel to go back in time to before you used the shield, it's as close to a full round as you'll need.
Maybe I'm missing something. Shield is an immediate interrupt, right? This means you don't use it during your turn. Thus, by strict definition it will never last a full round. If, as I said earlier, you happen to act after the person that caused you to want to trigger shield then the shield will only be used once (unless you happen to provoke). For instance:
Bad guy attacks you --> you use shield
You act, shield ends
Bad guys 2-5 act --> shield is useless
You'll only ever get (near) maximum usage if you happen act before the bad guy that's causing you to trigger.
