Understanding 38 CFR 4.16(a) and (b)

38 CFR § 4.16(a) describes percentage requirements and inability to secure or follow substantially gainful employment due to service-connected disabilities.
38 CFR § 4.16(a) also addresses marginal employment, including income and the circumstances of employment.
38 CFR § 4.16(b) addresses referral for extraschedular consideration when the percentage requirements are not met and service-connected disabilities prevent substantially gainful employment.
This comparison does not establish entitlement or predict a VA decision.
