====Distance====

The documentation will sometimes refer to //distance// when it comes to correcting lag. 

Although distance-between-sensors is one of the most common causes of lag, please note that you don't have to be dealing with actual length measurements when we refer to distance.

The [[source|source of your lag]] could be looking at //any// rate or total, such as liquid or gas flows, pollution levels, number of produced units etc.

When the documentation refers to 'distance', we mean **the difference in the source value between two points**.

For example, there might be a pipe between machine A & B which has a volume of 27L. If you're compensating for lag using the //flow of liquid through your system //, that 27L would be the **distance from A to B**.

You choose a distance when calling [[lcq_AddQuery|AddQuery]].
