We never see the characters go to the bathroom. So they must never go to the bathroom.
We never see Yoda teach Luke how to build his lightsaber, so Yoda must never have taught Luke how to build his lightsaber.
Unless, of course, you meant something else when you stated that.
"Read the novelization again ... I believe Lando is the one who determines the time frame, but it's determined in the Jabba portion of the book."
Quote
Lando had managed to infiltrate this nest of maggots month's earlier to see if it was possible to free Solo from Jabba's imprisonment. He'd done this for several reasons.
First, because he felt (correctly) that it was his fault Han was in this predicament, and he wanted to make amends-provided, of course, he could do so without getting hurt. Blending in here, like just one of the pirates, was no problem for Lando, though-mistaken identity was a way of life with him.
Second, he wanted to join forces with Han's buddies at the top of the Rebel Alliance. They were out to beat the Empire, and he wanted nothing more in his life now than to do just that. The Imperial police had moved in on his action once too often; so this was a grudge match, now. Besides, Lando liked being part of Solo's crowd, since they seemed to be right up at the business end of all the action against the Empire.
Third, Princess Leia had asked him to help, and he just never could refuse a princess asking for help. Besides, you never knew how she might thank you some day.
Finally, Lando would have bet anything that Han simply could not be rescued from this place-and Lando just plain couldn't resist a bet.
So he spent his days watching a lot. Watching and calculating. That's what he did now, as Chewie was led away-he watched, and then he faded into the stonework.
Of course, this doesn't even take into account the time Lando spent just finding Han.

Seems to me that, once again, you are trying to read the worst case scenario into these films. I'm getting the distinct impression you don't like any of the films.
