I'm currently reading over 500 and only get around 12 - 20 updates a day. Translating and editing simply takes a lot of time and effort so we just gotta have patience to endure the wait and appreciation for each upload a scantalation team makes.
Reading 551 manga and I got generally 5 updates a day (10 when it's a nice day), it depends of what you followed (dropped or actually translated) and yes, translating is a long and painfully road :)
Can someone explain how I can read 130 mangas but having no updates to the mangas? ┑( ̄Д  ̄)┍
