Do Iron accounts have to stay at Tempoross until a Fish Barrel drops?
No. The barrel remains a permit reward, but it can also be bought for 6,000 Spirit Flakes. Choose Tempoross for its broader rewards only when that fits your route.
OSRS Mining Training Planner
Why is Zalcano time marked variable?
Reward mode, XP mode, team, contribution and kills per hour change the result too much for one honest planning rate.
How idle are Shooting Stars?
Each layer lasts seven minutes while it is being mined, though moving between layers and stars still needs attention.

Why is birdhouse time not shown as normal Hunter XP per hour?
A run is brief but the houses need 50 minutes to mature. The planner shows XP per run, active-time equivalent and real elapsed schedule time separately.
Why can my Rumour rate differ from the planner?
Task blocks, teleports, whistles, Hunter Guild outfit pieces and execution create a wide gap between expected and maximum rates.
