Feels a bit 'how many angels can dance on the head of a pin' to me.
In movies, TV shows and RPGs, travel mostly happens by 'speed of plot'. In the Star Wars films, we don't see a lot of travel; mostly Han just says 'we need to go to Planet Z!' and there's a screen wipe to the Falcon arriving there.
Okay, some RPGs like 'One Ring' make the travel the focus of the adventures, and they have lots of skills and talents for it.
But serious question here... How many of you are really obsessing about this stuff at the gaming table? Do you make the players intricately plan out their routes, or just handwave it with an Astrogation check? If you spend a lot of time on this, won't the other players get bored? Unless the whole adventure is a race or something, does it matter how long a journey takes anyway? Most of the time, don't we just say 'okay, you've travelled to the planet you need to be on, now you're here.' Long travel scenes and lots of dice-rolling on minor stuff doesn't usually make for exciting pulp sci-fi adventures, surely?
It strikes me that Lucas just had Han talk about the Kessel Run as something cool to say. "I did this difficult thing in record time, because I'm so badass'. I don't think he knew what a 'parsec' was or had any specific distances in mind.
