Formula Used

Projected runeys = Current + Days × (Daily Added − Daily Removed + Support Effect − Drain Effect).

Support Effect = Supporting Type Count × Support Rate. Drain Effect = Consuming Type Count × Drain Rate.

The planning cycle is water supports grass, grass supports tree, tree supports rock, and rock supports water. The next type creates drain pressure.

Gap = Target − Projected. A positive gap means add runeys. A negative gap means remove runeys.

Ecosystem Score is the average target closeness score for all four runey groups.

Runey Planning Guide

Why Balance Matters

Runey planning is a small math problem with daily consequences. Each area has four visible groups. Grass, tree, rock, and water runeys must stay near useful targets. A weak group can lower the area score. A strong group can create surplus that should be moved. This calculator turns the map review into clear numbers. It compares current counts with chosen goals. It also projects several days ahead. That helps you plan before the next route.

Reading the Counts

Start with the current count in one area. Then set target values that match your strategy. Many players use equal targets for calm planning. Others keep a higher grass buffer. The safe minimum protects against sudden drops. The maximum cap marks overflow risk. The prosperity minimum marks the count needed for a comfortable zone. These values are editable because each save file can feel different.

Using Projections

The projection uses manual gains, removals, support, drain, and days. Support rate rewards a type when its feeder is strong. Drain rate estimates pressure from the next type. The model is not a hidden game engine. It is a planning model. It gives a repeatable estimate for transfers. Use it to decide which runeys to collect, release, or leave alone.

Better Daily Routes

Good routes are simple. Visit the weakest area first. Add the largest deficit next. Remove obvious surplus after that. Check the score after each change. Save notes for repeated patterns. If water falls often, adjust its target higher. If rock overflows, reduce the target or harvest more. The daily move column gives a practical pace. It spreads the gap across your planning window.

Advanced Strategy

Use the ecosystem score as a quick warning. A low score means the area is far from target. The volatility value shows how uneven the groups are. High volatility means one type dominates. The priority action highlights the largest correction. Combine that result with your own route timing. The best plan is stable, repeatable, and easy to follow. Recheck counts often, because small errors can grow quickly.

Record yesterday’s final counts. Compare them with today’s totals. This habit reveals trends early. Problems stay smaller across areas. Long seasons become easier daily.

FAQs

What does this runey calculator do?

It compares current runey counts with your target counts. It then projects future totals, finds shortages, marks surplus, and suggests transfer actions for each type.

Is this an exact game engine simulation?

No. It is a planning calculator. It uses adjustable support and drain rates so you can model a route strategy and review likely balance problems.

Which runey types are included?

The calculator includes grass, tree, rock, and water runeys. Each type has current, target, daily add, daily remove, and projected result fields.

What does a positive gap mean?

A positive gap means the projected count is below your target. Add that many runeys, or divide the daily move amount across your planning days.

What does a negative gap mean?

A negative gap means the projected count is above your target. Remove that surplus, move it to another area, or lower your daily additions.

How should I set the target count?

Use equal targets for simple planning. Raise a target when a type keeps falling. Lower a target when that type often creates surplus.

What is the ecosystem score?

It is an average closeness score. Higher values mean projected counts are nearer to your chosen targets and easier to manage.

Can I save the result?

Yes. Use the CSV button for spreadsheet notes. Use the PDF button for a simple route sheet you can keep with your planning records.
