Stats Guide

The stats in Umamusume involve a lot of math. Before getting into that, let’s briefly look at what each stat does.

• 

  Speed
  increases your top speed during the last third of the race. It does nothing before that.
• 

  Stamina
  increases your uma’s HP. When she runs out of HP, her speed drops to the minimum value. Having more than you need for the race does nothing on its own, aside from protecting you against things like debuffs and Rushed.
• 

  Power
  increases your uma’s acceleration, as well as her speed while running uphill. It does nothing to help you get unblocked, despite what the game’s own tips say.
• 

  Guts
  reduces your HP consumption during the last third of the race. This makes it function very similarly to
  

  Stamina
  , but is usually weaker, especially in large quantities.
• 

  Wit
  does a variety of other things, sometimes acting as a luck stat. Most notably, it affects how often your skills trigger, but it also affects your speed throughout the race, your chance of getting boosts on downhills, and your chance of becoming rushed.

For most people, those overviews should be enough. But, if you want to dive deeper, let’s get into…

Speed

Your uma’s base speed is determined by this formula:

BaseSpeed = (20 - (CourseLength - 2000) / 1000) * PhaseModifier

The PhaseModifier varies based on the style at different points in the race. It covers things like Front Runners being stronger early on, and End Closers being stronger later. You can get the value from this table:

Then, in the final leg, it becomes this:

FinalLegSpeed = BaseSpeed + sqrt(500 * Speed) * DistanceAptitude * 0.002

If your uma has enough HP, she will go into spurt mode, which uses this formula:

MaxSpurtSpeed = (FinalLegSpeed + 0.01 * BaseSpeed) * 1.05 + sqrt(500 * Speed) * DistanceAptitude * 0.002

DistanceAptitude will usually be 1, for an A rank, or 1.05, for an S rank. S is roughly equivalent to raising your

stat by 10%.

Stamina

and HP

Your uma’s HP is determined by this formula.

Max HP = TrackDistance + (Stamina * 0.8) * StyleModifier

StyleModifier is based on your uma’s running style.

• Front Runner: 0.95
• Pace Chaser: 0.89
• Late Surger: 1
• End Closer: 0.995

This means Pace Chasers receive 11% less HP from their

than Late Surgers. Recovery skills restore a percentage of your max HP, so with the same , Pace Chasers will also be restoring less HP from their recoveries.

HP is consumed according to the following formula:

HP Per Second = 20 * (CurrentSpeed - BaseSpeed + 12)^2 / 144

So, the faster your uma is running, the more HP she uses. Since she runs slower on uphills, this means that uphills take less HP compared to flat land, which is a bit unintuitive.

Power

Your uma’s acceleration is determined through the following formula:

Acceleration = BaseAcceleration * sqrt(500 * Power) * PhaseModifier * SurfaceAptitude

BaseAcceleration = 0.0006 normally, 0.0004 on uphills. Like Speed, SurfaceAptitude is usually 1 for A rank, and 1.05 for S rank.

Also just like

, there’s a PhaseModifier for acceleration. It follows a similar pattern to the Speed one:

When running uphill, your uma’s speed is reduced according to this formula:

Speed Penalty = |100 * tan(angle in radians)| * 200 / Power

The more

you have, the faster you run when going uphill.

---

Guts

During the last third of the race, your HP consumption rate is changed according to your

:

HP Consumption Multiplier = 1 + (200 / sqrt(600 * Guts))

More

results in less HP being consumed. Since your max HP is increased by the track’s distance, each distance has a different threshold at which becomes better than in terms of letting you survive.

So, if you have less

than this number, one point of gives you more effective HP than one point of , and vice versa when above it. Basically, this is 80 + (Distance / 100).

Wit

does various things. First, it affects how often your skills activate, according to this formula:

Trigger Percent = 100 - 9000/Wit

Here’s a chart across some values of

. It increases quickly, then tapers off.

It also affects your chance of becoming Rushed. Rushed makes your uma run forward and increases their HP consumption by 60%. The chance is:

Rushed Percent = (6.5 / log10(0.1*Wit+1))^2

Here’s another chart. Again, it starts sharply, then smooths out.

It also determines how fast your uma runs throughout the race. Every 1/24th of the track, the uma will roll between two numbers that are decided by her

, and use that to determine how fast to run.

Max Mod = Wit / 5500 * log10(Wit * 0.1)%

Min Mod = Max Mod - 0.65.

And here’s the chart.

This is relatively linear.

The downhill boost is perfectly linear. The chance is 0.04% per

you have. This is checked every second while running downhill, and if you’re in the boost state, you have a 20% chance each second to leave it.

Being in the boost state increases your speed based on how steep the slope is, with the following formula:

Speed Boost = 0.3 + |100 * tan(angle in radians)| / 10

On the shallowest hills, this is +0.4m/s. It also reduces your HP consumption by 60% while in it.
