It works as a way to settle; it is weak as a way to test contact. When a narrator tells you to see a cottage, your mind produces a cottage. When the script says a guide is approaching, your mind knows what comes next. That does not make meditation bad. It means the format mixes suggestion and experience so closely that you cannot easily tell them apart.
The live Call Your Guide Challenge wins for anyone who wants contact they can check, follow-up questions, and a clear answer by Day 5. A recording genuinely fits a narrower case: relaxing at home on your own schedule, with no plan to ask your guide anything specific yet.
