You reject my argument and then go about saying something just as subjective, imagining different lengths of burning time.
I see holding times while being punished, tormented in flame, before the Lake of Fire based on scriptures like the "uninterpreted parable of the rich man and Lazarus" as you put it and I see places of blessing for the righteous based on the same parable, and the promise to the thief on the cross and even Paul's expectation to be with Christ upon death, and you see different burning times in the Lake based on sins, based on what? From what "parable, or text?" Who is inventing things? At least I have a reason. You are just imagining what you think seems fair and we know how reliable our own reasoning can be right?
I mean if you are going to imagine things like that at least use a verse. Maybe something like this one in Luke 12
45But suppose the servant says to himself, ‘My master is taking a long time in coming,’ and he then begins to beat the other servants, both men and women, and to eat and drink and get drunk.
46The master of that servant will come on a day when he does not expect him and at an hour he is not aware of. He will cut him to pieces and assign him a place with the unbelievers.
47“The servant who knows the master’s will and does not get ready or does not do what the master wants will be beaten with many blows.
48But the one who does not know and does things deserving punishment will be beaten with few blows
Maybe in your scenario they are in the Lake of Fire and being beaten with flaming whips, only some get beaten for millions of stripes and some less. (my run away imagination again)
