How to Read Comp Stats on tactics.tools: Placement, Top 4 %, Win % and More

On tactics.tools, a comp's strength is summarized by four numbers: Place, Top 4 %, Win %, and Play Rate. Place (average placement) tells you the typical finish, Top 4 % tells you how often the comp converts into a points finish, Win % tells you how often it wins the lobby outright, and Play Rate tells you how contested it is. Read them together, not one at a time — a high Win % on a tiny Play Rate means something very different from a high Win % on a heavily contested comp.

The core metrics, defined

The site groups comps under labels like Core Flex, Fast Level 8, Level 7 Reroll, and Level 5 Reroll, and tags them with notes such as Items Dependent, Consistent, or High Win %. Those tags describe how the comp is played and what it needs, so treat them as part of the stat line rather than decoration.

Worked example from the site

The Top Comps list shows entries like:

• Riftbeast Amumu & Aphelios — Core Flex, Play Rate 0.71, Place 4.26, Top 4 % 55.2, Win % 12.5, Fast Level 8, Items Dependent, Consistent
• Spellweaver Veigar & Ornn — Core Flex, Play Rate 0.50, Place 4.30, Top 4 % 53.3, Win % 15.8, Level 5 Reroll, Items Dependent, High Win %

Both have similar average placements (4.26 vs 4.30), but they are not the same kind of comp. The Veigar & Ornn line has a noticeably higher Win % (15.8 vs 12.5) while finishing slightly worse on average — that pattern fits a reroll comp that either spikes hard or misses. The Amumu & Aphelios line has a higher Top 4 % (55.2 vs 53.3), which fits a more consistent fast-level-8 comp. If you want steady points, the second profile is usually the safer read; if you need firsts, the first profile is more attractive.

Judging consistency vs. ceiling

• High Top 4 %, moderate Win % → consistent, low-variance comp. Good for climbing.
• Lower Top 4 %, high Win % → high-roll comp. Good for lobbies where you need a first, riskier for steady gains.
• Place close to 4.5 with a low Play Rate → often a niche or under-explored comp; the sample may be thin.
• Place well below 4.0 → usually a sign the comp is either very strong or being played only in favorable spots.

A single number can mislead. A comp with a 4.26 Place but a 0.09 Play Rate (as with Blossom Master Yi) is being played rarely, so its stats rest on far fewer games than a comp at 0.71 Play Rate. Treat low-Play-Rate numbers as provisional.

Sample size and patch changes

Two things move these numbers more than anything else:

1. Sample size. Play Rate is your proxy for it. A comp at 0.71 Play Rate has far more games behind its stats than one at 0.09. Low-play comps can swing several tenths of a placement from a handful of results.
2. Patch version. The site labels comp data by patch (for example, "Top Comps (18.3b)"). When a new patch drops, old numbers describe a game that no longer exists. Always check which patch the stats belong to before acting on them, and give fresh data a few days to accumulate before trusting it.

The site also surfaces Trends — comps with a placement delta shown in parentheses, like 3.63 (+0.46) or 4.58 (-0.16). A positive delta means the comp's average placement has gotten worse; a negative delta means it has improved. This is the fastest way to spot a comp rising or falling within a patch.

A practical reading order

1. Check the patch label on the comp list.
2. Filter by Play Rate to separate well-sampled comps from niche ones.
3. Compare Place and Top 4 % for consistency.
4. Check Win % if you specifically need firsts.
5. Check the Trends delta to see if the comp is moving up or down.
6. Read the tags (Core Flex, Reroll, Items Dependent, Consistent) to understand what the comp demands from you.

Used this way, the numbers tell you not just whether a comp is strong, but whether it fits how you need to play the lobby.
