"For five minutes" and "for two weeks" are both durations which can be used with the Past Perfect Continuous. Notice that this is related to the Present Perfect Continuous; however, the duration does not continue until now, it stopsbefore something else in the past.

Past Continuous vs. Past Perfect Continuous
If you do not include a duration such as "for fiveminutes," "for two weeks" or "since Friday," many English speakers choose to use the Past Continuous rather than the Past Perfect Continuous. Be careful because this can change the meaning of the sentence. Past Continuous emphasizes interrupted actions, whereas Past Perfect Continuous emphasizes a duration of time before something in the past. Study the examples below to understand the difference.Examples:
• He was tired because he was exercising so hard.
This sentence emphasizes that he was tired because he was exercising at that exact moment.
• He was tired because he had been exercising so hard.
This sentence emphasizes that he was tired because he had been exercising over a period of time. It is possible that he was still exercising at that moment OR that he had just finished.It is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. Instead of using Past Perfect Continuous with these verbs, you must use Past Perfect.
• The motorcycle had been belonging to George for years before Tina bought it. Not Correct
