# Endurance

## Repair cost reduction

At each upgrade point, tire repair cost decreases by 0.15\~0.2%

## Examples

### Daily reward distance = 100km

* Endurance point 0 (default repair cost factor = 10%)

Repair cost at full daily use = 100 \* 0.1 = 10 SDT

\=> Repair cost per 1 energy = 1 SDT

* Endurance points 20. Possible repair cost factors 0.06\~0.07 (6\~7%)

Repair factor = 0.065 (6.5%)

Repair cost at full daily use = 100 \* 0.065 = 6.5 SDT

\=> Repair cost per 1 energy =  0.65 SDT (Cost less to repair)
