1. Concentration claim (one sentence)
On recreational alpine slopes, most control gains and most preventable trouble concentrate in a few repeatable moment-types - boot-to-ski balance, speed before the turn, linked edge engagement, catch-and-recover, and skill-matched terrain/visibility - while equal polish of every tip, endless vertical, and gear shopping concentrate into motion.
2. Hard anchors (2–5)
- Hulme et al. (2015), Sports Medicine — Meta-analysis of recreational snow-sports risk: beginner skiers OR 2.72 (90% CI 2.15–3.44); rented equipment OR 2.58; poor visibility OR 2.69; helmets associated with lower head-injury odds (OR 0.58). Beginners’ injuries primarily from falls (vs jumps for more experienced). https://pubmed.ncbi.nlm.nih.gov/25946993/
- Sulheim et al. (2011), British Journal of Sports Medicine — Case-control (Norwegian resorts): beginners elevated overall injury risk (OR 2.72); knee injuries more frequent among beginners (OR 3.13). https://doi.org/10.1136/bjsm.2011.085126 · PDF: https://klokeavskade.no/globalassets/publications/sulheim_2011_bjsm_risk-factors-for-injuries-in-alpine-skiing-telemark-skiing-and-snowboarding-.pdf
- Posch et al. / ACL mechanism literature — In recreational alpine skiing, ACL affected in ~50% of serious knee injuries; forward fall with body rotation commonly reported as a dominant non-contact ACL mechanism (~63% in one ACL-injured cohort). https://pmc.ncbi.nlm.nih.gov/articles/PMC9989403/ · https://pmc.ncbi.nlm.nih.gov/articles/PMC9165279/
- Boot as force-transfer interface — domain systems fact (tight, balanced fit enables edge control); cite Frontiers on-snow boot/closure work as performance/fit evidence, not a brand endorsement. https://doi.org/10.3389/fspor.2023.1192737
- Fall-tag protocol after near-falls / falls — personal measurement, not a lab dataset.
2b. Field 80/20 examples
| Approx % claim | Field / context | Source | Where |
|---|---|---|---|
| Beginner skier OR ~2.72 vs non-beginners | Recreational injury risk | Hulme 2015 / Sulheim 2011 | Terrain + skill bottleneck |
| Rented equipment OR ~2.58; poor visibility OR ~2.69 | Recreational injury risk | Hulme 2015 | Boot/setup + visibility moments |
| Helmet OR ~0.58 for head injury | Countermeasure | Hulme 2015 | Close / chaos filter |
| ACL ~50% of serious knee injuries; forward twisting fall common | Recreational ACL | Posch et al. line | Catch-and-recover / edge |
| Illustrative: top 2 fall tags = 12/20 = 60% | Personal measurement | Illustrative | Only-on-8020 |
Never invent “80% of ski improvement comes from 20% of runs.”
3. Original observation (only-on-8020 seed)
Fall-tag log: after each fall or scary near-fall (or after a run that felt out of control), one tag: stance | speed | turn | edge | terrain | boot. Twenty tags; drill the dominant tag.
4. Ignored majority (named)
Chasing vertical on terrain above skill; gear shopping before boot fit; tip-of-the-week scrolling; skiing tired late-day ice; equal practice of every park trick before linked turns work; ignoring helmet / visibility.
5. Composite policy
| Scenario | Keep as Illustrative? |
|---|---|
| 20-tag fall log sample | Yes |
6. Vital few (≤5)
- Boot fit + athletic stance over the skis
- Speed management before committing to the turn
- Linked turn / edge engagement (not panic skids)
- Catch-and-recover (edge catch → safe stop / controlled fall)
- Terrain & visibility matched to today’s skill and conditions
7. Device budget
≤5 bottlenecks · one named drill each · ≤2 example/move pairs · viz: none
7b. Viz & misreads
Viz: none Traps: 3 (more vertical = more skill; soft boots = comfort first forever; “I can handle that blue if I go faster”)

9. Sign-off
- ☑ Brief complete
- ☑ No invented “80% of falls from X” without source
- ☑ Not a lesson plan replacing a certified instructor; not medical advice
