Hey guys your wrong it isn't writtent incorrectly, poorly, nor gives misinformation. You just reading it wrong or taking it to literally. This is a short hand term, and serves its purpose. I gave several examples of how it is correct. The phrase "at a time" does not mean what OP said it does. It is hard for me to explain it well. So I will go with my movie rental example.

Yo go to a new movie rental place and ask, "how many movies can I rent out" He will reply " you can only rent out three movies AT A TIME" This doesn't always mean you rent three come back rent three more. But for every time you do rent out movies you can get 3.

Another exampke again, is the lioness giving birth to cubs. Which they tend to give birth to, two cubs at AT A TIME. does this mean they have non stop babies? no. It means every time they do become pregnet and give birth it is typicall only 2 cubs. (or more it been a while).


So again what npc said is correct info. Just you lot missunderstood it, and took it to literal.
