# Stats and Earn Rate

## Stats

Each Catto NFT has two types of stats: 

* **Static Stats** are fixed.
* **Generated Stats** are computed from static stats and other NFT properties.

### Static Stats

**Smartness\[S]:** Smartness impacts the daily reward cap.

**Vitality \[V]:** Vitality impacts stamina consumption.

**Dexterity \[D]:** Dexterity impacts earning speed.

**Curiosity \[C]:** Curiosity impacts the rate of experience accumulation.

**Luck \[L]:** Luck may impact places related to probability.

#### Static Stats Value Range

When a Catto NFT is minted, static stats will be assigned a value within a range that depends on the NFT Tier. All three static stats share the same value ranges based on the NFT Tier.

| Tier   | Min Stat Value | Max Stat Value |
| ------ | -------------- | -------------- |
| Tier 1 | 3              | 8              |
| Tier 2 | 8              | 16             |
| Tier 3 | 16             | 28             |

### Generated Stats

**Daily Reward Cap**

There is a daily reward cap for each Catto NFT, which is computed from the following formula:

**Stamina Consumption**

For every true-reading minute users spend on ReadON, equipped pets will consume stamina.  The amount of stamina consumed per minute is computed from the following formula:

**Earning Speed**

For every true-reading minute users spend on ReadON, they will accumulate $READ, up to the daily earning cap of the Catto.

#### Rate of Experience Accumulation&#x20;

For every true-reading minute users spend on ReadON until the daily reward cap is met, the equipped Catto NFT will accumulate experience (EXP). The amount of EXP per minute is computed based on the following formula.

## **Multiple** Catto **NFT Stacking**

For users with multiple Catto NFTs, only one pair can be equipped at a time as the Primary NFT. All other pairs of Catto will be displayed in the user’s inventory and will accumulate $READ and EXP at the reduced rate shown below.

| Number of NFTs in the inventory | Reduced Ratio |
| ------------------------------- | ------------- |
| 2-3                             | 0.7           |
| 4-7                             | 0.5           |
| 8-11                            | 0.3           |
| 12-15                           | 0.15          |
| 16+                             | 0.1           |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://whitepaper.readon.me/read-fi-token-economy/read-fi-mechanism/stats-and-earn-rate.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
