If the drain time of each difficulty is...
- cases
- Difficulties lower than the highest difficulty can use their play time as a metric instead of drain time if their drain time is at least 80% of their play time.
The only different between play time and drain time is the inclusion of breaks. This extra condition here implies that >20% of added break time is "too much" for a lower difficulty, yet this is entirely dependent on how the beatmap plays and I don't think it's right to set a hard& arbitrary limit here.
