Basic Rules wiki:

You can receive rewards depending on the number of LAPs you complete before the total time reaches 0.
The key is to clear LAPs as quickly as possible.

Entry Gunpla wiki:
You will enter one special Gunpla when you attempt each LAP.
When you clear the LAP, your clear time and entered Gunpla will be recorded, and you will no longer be able to use the parts in that Gunpla during that Battle Circuit.■Usage Count
Each part has a usage count, with each LAP entry reducing the part’s usage count by 1.
Parts that reach 0 can no longer be used in the Battle Circuit currently being held.
(If the entered Gunpla is overwritten by another Gunpla through a replay, you will be able to use it again.)Each part’s usage count is 1 by default, but for each increase in the part’s EX Skill Lv or Part Trait Lv, the usage count will also increase by 1.
Ex: If a part with EX Skill Lv 5 is used, that part can be used in a total of five LAPs.
■Gear Entry
Gear can be equipped to entered Gunplas.
As a rule, Gear used once in the current Battle Circuit cannot be used again.

Gundam breaker mobile Replaying wiki:

You can replay LAPs that you have completed as many times as you want.
You will be able to reuse parts that were used with the Gunpla entered in that LAP or parts not registered in other LAPs.
If you replay a LAP, you can choose to overwrite the recorded clear time and entered Gunpla.
Try to shorten your time and effectively reuse parts from early stages in the later LAPs.
