Basically every single tapering study that maintained exercise intensity and dropped volume sufficiently (~40-80% drop) for ~1-4 weeks has …

what it claims

To optimize performance, it is recommended to maintain training intensity while significantly reducing volume (by 40 to 80%) over a period of 1 to 4 weeks before a target event.

holds up

This recommendation is based on solid foundations in exercise physiology. Meta-analyses, notably those published by Bosquet et al.

This recommendation is based on solid foundations in exercise physiology. Meta-analyses, notably those published by Bosquet et al. in 'Medicine & Science in Sports & Exercise', confirm that this 'tapering' strategy allows for the dissipation of accumulated fatigue while preserving neuromuscular and cardiovascular adaptations. Maintaining intensity is crucial, as it is the primary signal that tells the body to retain its gains in strength and speed. Reducing volume, meanwhile, facilitates the supercompensation of energy reserves and tissue repair. The assertion that the method is 'beyond reproach' is a strong stylistic turn of phrase, but it accurately reflects a robust scientific consensus. Evidence from randomized controlled trials (RCTs) broadly supports this 1 to 4-week time frame as optimal for the majority of athletes.

What the graded evidence says

Evidence: C

Effect: performance after tapering; sleep interventions for recovery — tapering associated with small performance improvements in endurance athletes; sleep extension/hygiene shows promising but heterogeneous recovery benefits
Measured on: trained athletes; general active adults

Recovery matters, but the evidence for any exact deload frequency is limited. Sleep and nutrition support recovery; the specific numbers people cite are rules of thumb, not established doses.
