That's an odd question, really. It all depends on the context and the type of changes, obviously.

If it's a critical fix, then it goes out asap. If it's a minor fix, but relating to a new feature roll-out from 2 hours ago, it too goes out as soon as it's ready. Otherwise, changes gets deployed once the feature is complete.

I understand what you're saying, but I think the OP meant how often do you deploy on average. That is, take all the deployments you mentioned, regardless of the reason they happened, and average out.
