# Future Improvements
### Correct Usage
In the current design, each epoch should be at least two blocks, as the start block should be different from the endblock. Because of this, the time allocated to each epoch will be `max(block_time x 2, epoch_duration)`. For example: if the `epoch_duration` is set to `1s`, and `block_time` is `5s`, actual epoch time should be `10s`.
It is recommended to configure `epoch_duration` to be more than two times the `block_time`, to use this module correctly. If there is a mismatch between the `epoch_duration` and the actual epoch time, as in the example above, then module logic could become invalid.
### Block-Time Drifts
This implementation of the `x/epochs` module has block-time drifts based on the value of `block_time`. For example: if we have an epoch of 100 units that ends at `t=100`, and we have a block at `t=97` and a block at `t=104` and `t=110`, this epoch ends at `t=104`, and the new epoch will start at `t=110`.
There are time drifts here, varying about 1-2 blocks time, which will slow down epochs.

## 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://docs.blockxnet.com/protocol-developers/modules/epochs/future-improvements.md?ask=&goal=
```
`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.
