Agreed, though personally this part of the story felt (to me at least) like it was played out in more or less real time. Lando tells them theres still time to save Han, they go running off to do so.....and its not like Fett was gonna be waitin around for anything...once his bounty was loaded onboard he'd be outta there.
On another note I just noticed that the stormtrooper that Chewie takes out after the departure of Slave1 moves quite a far distance across the floor between shots......all while suffering from a laser blast to the armour (which as you all know is instantly fatal to ST's)
