Gravel plan vs in season plan

Is the gravel plan more of a CTL builder, and the Gravel in season Plan a more CTL maintain plan with higher intensity intervals?

The In Season Gravel plan is more for the athlete that already has a high CTL because they have already raced their first big gravel event. From the product description:

Our Gravel In-Season Training Plan is for the athlete who’s already raced one of their big gravel races and wants to train for their next gravel event later on in the season

This gravel plan focuses on helping you recover from the weekend’s training and balances the mid-week structured sweet spot and tempo interval workouts. On Saturdays the Gravel simulation rides will test out your equipment, your pacing + your nutrition and hydration as Coach Frank and Jackson have podcasted about.
