== When NOT to use this pattern ==
The thing about using the pattern above is that it's expected that the activity is done ''regularly'', as part of a ''habit''. If it's not an activity that's regularly engaged in, it's weird to use the pattern. Consider the following examples:
* 你 ''多 长 时间'' 换 ''一 个'' 手机 ?How often do you buy a new cell phone?
* 你 ''多 长 时间'' 加 ''一 次'' 班 ?How often do you work overtime?
* 你 ''多 长 时间'' 吃 ''一 次'' 牛油果 ?How often do you eat avocado?
In these cases, the speaker is trying to get any idea of how often the other person does something, regardless of how regular or habitual it is. In this case, just use 经常 (or similar) to ask about it.
* 你 '''经常''' 换 手机 吗 ?Do you often buy a new cell phone?
* 你 '''经常''' 加班 吗 ?Do you often work late?
* 你 '''很 少''' 吃 牛油果 吧 ?You rarely eat avocado, right?
