Does anyone think that Admiral Ozzel was already screwed prior to coming out of Hyperspace too early?
The Rebels already knew the Imperial Fleet was coming for them after they found the remnants of the Imperial Probe Droid. They began evacuation procedures prior to the fleet coming out of Hyperspace. My contention is that no matter where Ozzel would have came out of hyperspace, it would have looked like to the Empire that they had been "alerted to their presence."
Now Ozzel had blundered already (we saw the second guessing by Piett after the Probe photographed the shield generator in ESB), and probably had done so prior to the past, (Vader's words, "You have failed me for the last time.") So no matter what he would have done, he would have been doomed to die by a Vader force choke.
