Replying to Fastest progression you’ve seen in an adult

So one of my buddies recently picked up skiing, has probably been about 20 days in his entire life, and he looks super comfy carving around, popping of knuckles, and all that other fun shit. The other day the kid even started doing some pretty decent ones, and sliding the fatter, more basic tubes and bars with relative ease and comfort. Ive definitely never personally known someone who became somewhat proficient on skis in that short of time, and I was wondering if any of u guys have a homie that picked up skiing as a teen or adult, and developed some sauce relatively quickly

*bonus points if they don’t have a gymnastics/action sports background
