Remember that barely than is incorrect; barely when refers to time frames.
Barely implies a minimal amount, while when indicates time or circumstance.
To recall correct usage, associate barely when with instances needing time or timing; than is not used with barely.
Avoid using than after barely, it's a mix-up with comparative constructions.
When using barely, make sure it sets the minimal conditions for something specific, often related to time with when.
