how about you read the page then? it's all on there:

A Manic will almost always spawn after 14 to 16 minutes in a Grineer Survival mission, or after about 5 Excavators in a Grineer Excavation mission.

In the mission Titania, Uranus where you have to kill Tyl Regor they have the best spawn rate almost 1 every time you run that level.
