How many request takes to get the followers ids?

[Arturo Herrero]

I'm exceeding the Twitter API rate limits when I try to find the followers of some users. It's depends of the users that I try to query I get the exception, I suppose that depends of the number of followers that a user has. This is my code:

client.follower_ids(user_id).to_a

Reading the documentation GET followers/ids, I understand that I consume one request for each user that I take the followers. So, I can query 15 times per 15 minutes if all the users has less than 5000 followers but I thing that there is something wrong in my conclusion.

Can someone put some light on my issue and understanding of the Twitter rate limits?

Thanks.
