For Gem Grab, this map's mode — duels and star rates are available per mode, not per map.
On the tier: counter safety and star rate are computed across all tiers together and do not change when you switch — too few pairings are measured in Masters for that. The other axes do.
Only Hard Rock Mine. 08/04 to 08/11, 6 days. 16 earlier days are left out — below 60 appearances a daily win rate is noise. One point per day. Both curves scale to their own range; the numbers on the left and right are the values for 08/04 and 08/11.
Win rate per rank tier on Hard Rock Mine — ranked battles only, the tier comes from the battle itself. The axis runs from Gold to Masters, one tick per tier: the stretch where this brawler has at least 300 battles per tier; 3 tiers fall below that and drop out. The stretch always fills the full width, three tiers or eight — so when comparing two curves, mind the names on the axis. The curve glows brighter where more was measured — the tiers differ by more than a thousandfold in battles. The faint horizontal line sits at 50 %.
Skill bonus −3.2 — punishes weak opponents: from Gold to Masters the win rate drops by 3.2 points (regression 51.3% to 48.1%). Higher up he gets outplayed.
Direct duels in Gem Grab: how Ruffs does when that brawler is on the enemy team. Duels are available per mode, not per map — so unlike the numbers above, this section covers every Gem Grab map, not just Hard Rock Mine. Computed across all ranked tiers together — not for your tier alone.
The word after the number says how hard: hard counter means the edge is clearly bigger than the strength of the two would give. A high win rate alone never appears here — whoever only wins because he is the stronger brawler does not make the list at all. See it in the counter network
On the same team, in Gem Grab — which combination wins. Per mode as well, not per map. Computed across all ranked tiers together — not for your tier alone.
