Does switching character after losing a game actually help?
Measured over 1,572,427 games · 19 August 2026
You drop game one. The rules hand you a counterpick, and with it the temptation to switch character. Everyone has an opinion about whether that works. Nobody seems to have counted.
We have the full game-by-game record of 870,660 Smash Ultimate sets, including which character each player used in each individual game. So we counted: after losing a game, how often does that player win the next one — and does switching change it?
The answer depends entirely on who you are
Pooled together, switching looks bad: 34.6% versus 38.3%. But pooling hides the real finding, because underdogs both switch more often and lose more often. Splitting by the rating gap — comparing underdogs with underdogs — the pattern reverses partway down.
| Their rating − opponent's | Kept character | Switched | Difference |
|---|---|---|---|
| below −400 | 4.7% (151,357) | 3% (29,295) | -1.7pp |
| −400 to −300 | 12.7% (106,036) | 8.7% (16,818) | -4.0pp |
| −300 to −200 | 20.6% (168,966) | 15.2% (22,840) | -5.4pp |
| −200 to −100 | 31% (242,818) | 25% (28,027) | -6.0pp |
| −100 to 0 | 43.1% (275,974) | 38.4% (29,734) | -4.7pp |
| 0 to +100 | 56% (224,897) | 54.3% (25,149) | -1.7pp |
| +100 to +200 | 67.3% (129,735) | 68.3% (16,711) | +1.0pp |
| +200 to +300 | 76.7% (55,498) | 79.2% (9,871) | +2.5pp |
| +300 to +400 | 83.7% (20,246) | 86.8% (4,931) | +3.1pp |
| above +400 | 90.4% (9,723) | 94% (3,467) | +3.6pp |
The gradient is clean and it crosses over between a 100 and 200 point rating advantage. If you are clearly the weaker player, switching costs you one and a half to six percentage points. If you are clearly the stronger player, it gains you one to four.
Why the strong get paid and the weak do not
A separate measurement on the same data explains it. We fit every player's rating on each character they play — how strong Glutonny is as Link, not how strong the average Link is. Almost everyone's secondary comes out weaker than their main, often by a hundred points or more.
So for most players, switching means moving to a character they are simply worse on, in the hope that the matchup makes up the difference. It usually does not. The players it works for are the ones with a genuine second character — deep enough that the switch is adaptation rather than a downgrade.
What this is not
This is an association, not advice. Players choose when to switch, and that choice carries information we cannot see: how one-sided the previous game was, what the stage was, whether they had a read. Someone who gets three-stocked and switches was probably losing that set either way, and we cannot separate the switch from the situation that prompted it. Nothing here says "do not switch" — it says players who switch while behind go on to win less often than players who do not.
Rating gaps come from our Whole-History Ratings, which are recomputed weekly over every set from start.gg. Games are restricted to sets where the complete sequence was reported, which is 99.9% of sets that have any game detail at all.
