You can store entries as much as you like, until you server runs out of memory.
The 1 you are passing, is the size of each Dynamic Array entry you are storing in the Dynamic Array.

1 is one integer, 2 are two integers in and array form.
So, if you use 2 or higher, you need to use ArrayGetArray and ArrayPushArray, to and add and remove them.
