How climber ratings work

SummitX maintains four independent ratings — Mastery, Form, Explorer, and Altitude. They evaluate different facets of your mountaineering experience, and it is normal to be strong in one and weaker in another: an experienced ice climber at low elevations and a high-altitude climber who avoids grade VI routes are simply different profiles, and both are valuable.

All four ratings are computed automatically from your history of confirmed ascents and are recalculated once a day: log an ascent today and you will see the updated numbers tomorrow.

Mastery

What it evaluates. Your technical ceiling — how difficult a wall you are actually capable of climbing. Only your best ascents count, not averages.

What raises the rating:

• Technically difficult routes.
• Leading the rope team — going first on every technical section, or at least on the crux pitches.
• Absence of fixed ropes on the route.
• Alpine style — completing the climb in a single push, without pre-fixed ropes or intermediate camps.
• A sufficient pool of different strong routes, rather than one or two isolated episodes.

What does not raise it:

• Repeat ascents of the same route — only your best attempt counts; the rest add almost nothing.
• Unsuccessful attempts and attempts that stopped before the crux.
• Routes for which we currently have weak or missing technical grading (see "How we grade routes").

When it becomes official. You need several different completed routes, some of them with a confident technical grade. Until then the rating is marked as provisional: the number is already being computed, but it is not yet compared with other climbers.

Form

What it evaluates. What you are capable of right now, not over your entire lifetime. Older achievements gradually lose weight, and newer ones move to the foreground.

What raises the rating:

• Recent strong ascents — climbs from the last year or two contribute their full weight.
• The same difficulty factors as in Mastery: technical difficulty, leading, alpine style.

What does not raise it:

• Old ascents. Their contribution fades over time: after a couple of years it is roughly halved, after four years it is reduced by about a factor of four.
• Variety of routes. Here strength matters, not breadth.
• Route rarity. For current form it makes no difference whether the route is popular or obscure.

When it becomes official. You need several different routes within the last two years. If you have not been climbing for a while, the rating stays provisional even if you had standout ascents in the past: Form is about what you are doing now.

Explorer

What it evaluates. The breadth of your experience: how many different routes, summits, and areas you have visited.

What raises the rating:

• Different routes — the more unique routes, the higher.
• Different summits — climbing a new summit counts for more than yet another route on one you already know.
• Different areas and major mountain regions — geography is tracked at two levels: individual valleys and massifs, and the larger mountain systems they belong to.
• Rare routes — a route that sees little traffic gives a small bonus when you climb it. Conversely, very popular routes have slightly less impact on the Explorer rating.

What does not raise it:

• Ten ascents of the same route.
• Ten routes on the same summit.
• Regular trips to the same area.

When it becomes official. You need several different routes, several different summits, and at least a few local areas or major mountain regions.

Altitude

What it evaluates. Your high-altitude experience as a separate axis — how high you have climbed and how technically serious those ascents were.

What raises the rating:

• High summits — the count starts at 2500 m, and the contribution grows non-linearly: 5000 m gives noticeably more than 3000 m, and 7000 m gives noticeably more than 5000 m.
• Different high summits — each new summit is counted once.
• Technically difficult routes at altitude.

What does not raise it:

• Summits below 2500 m are not counted toward the Altitude rating at all.
• Repeat ascents of the same summit — only the fact of "having been there" is counted.
• The presence of fixed ropes and siege-style ascents slightly reduce the contribution.

When it becomes official. You need several different summits above 2500 m, with the highest one you have reached no lower than 3000 m.

Two blocks on your profile: "Altitude experience" and the "Altitude" rating

On your profile you see two different altitude-related blocks:

• "Altitude experience" — counters such as "summits above 2500 m", "summits above 3000 m", "highest summit reached". These counters show all of your ascents, including routes for which we do not yet have our own technical grade (for example, ascents imported from external sources).
• "Altitude" rating — the rating number and your place on the leaderboard. It is calculated only from routes that have a completed grade.

Because of this, the number of summits "above 4000 m" on your profile may be noticeably larger than what feeds the rating. This is intentional: having visited a summit is part of your real experience, and we show it honestly. To keep climber-to-climber rating comparisons fair, however, only routes with a comparable technical grade are included in the rating itself.

How we grade routes

Each route receives a technical grade automatically, based on all recorded ascents. The quality of that grade depends on the number of records and how complete they are:

• Confident grade — the route has been climbed enough times and the pitch descriptions are complete. Such a route fully contributes to all four ratings.
• Low confidence — there are few records, or they are incomplete. The route still participates in the ratings, but with reduced weight.
• No grade — there is not yet enough data. Such a route is not included in the main ratings, but it still appears on your profile, counts toward your total number of ascents, and contributes to "Altitude experience".

To help a route reach a confident grade faster, provide complete information in your ascents: pitch types, their length, difficulty grades, weather conditions. Every detailed record helps — not only you, but also other climbers looking at the same route.

Rank, percentile, and the "provisional" status

Within each rating you see not only the numeric value but also your standing among other climbers:

• Rank — your position in the overall list. Rank 1 is the top of the rating.
• Percentile — the share of climbers you are ahead of. 95% means you are in the top 5%.
• Provisional status — applied when we do not yet have enough data to compare you fairly with the rest. The number itself already exists and is computed by exactly the same rules — you just should not draw conclusions from it yet. As soon as you meet the minimum requirements (several routes, and for some ratings several different summits or areas), the status automatically switches to official.

When ratings update

A full recalculation runs once a day across your entire ascent history. This means:

• If you logged an ascent today, you will see the recalculation tomorrow.
• If you refined the data on an older record, that will also be picked up at the next recalculation.
• If a number changed in an unexpected way, possible reasons include: the route does not yet have a confident grade; your ascent duplicates one that was already recorded; the ascent is very old and barely contributes to Form anymore.

The four ratings are not a competition but different ways of looking at your experience. Use them to choose a direction for growth: toward difficulty (Mastery), toward fresh form (Form), toward variety (Explorer), or toward altitude (Altitude).
