It's not about taking every single ranking as an absolute certainty - but it gives you an idea of the type of players and approx what range they should be in.
I think that Malkin/Forsberg are great comparables for Kucherov. And in 2019, they slotted 51 & 52. Malkin is probably a bit higher today. I'm of the opinion that Kucherov is having a better career than both of them - the question is has he already surpassed them, or is extra longevity needed? I'd say he's ahead, so I voted 41-50
The thing with Kucherov is - if he keeps adding seasons like this one, or adding 30+ point playoff runs, he will rise in huge leaps and bounds. He's a bit unpredictable. Curious to see where he ends up.
