HP

The HP calculation formula is (Track Distance) + (Stamina * 0.8) * (Style Modifier).

Front Runners have a multiplier of 0.95, or 95%, while Pace Chasers have one of 0.89, Late Surgers have one of 1, and End Closers have one of 0.995.

You might ask how Guts fits into this. Guts lowers your HP consumption at the end of the race. The multiplier for HP consumed is 1 + (200 / sqrt(600 * Guts)). More Guts means a lower HP consumption. You can see a graph of this here.

The base HP consumption rate is 20 * (CurrentSpeed - BaseSpeed + 12)^2 / 144

The track condition also affects this. The worst condition will give a 1.02 multiplier to HP consumed throughout the race, while the second worst gives 1.02 on Turf and 1.01 on Dirt.

While in Rushed, HP consumed is multiplied by 1.6. When you trigger the downhill boost, it’s multiplied by 0.4. When the uma enters pace down mode, it’s multiplied by 0.6. Front umas never enter pace down.

Recovery skills heal a percentage of your HP. A golden one will restore 5.5%, while a white will restore 1.5%. For Unique skills, if the uma is below 3 stars, it will restore 3.5%, otherwise, 5.5%.
