Abstract
Given a linear differential system which is not reducible as defined by Moser [6], we provide an improved estimate for the maximum growth order ρ of its solutions. Our proof relies on the results in [2] and a generalisation of the Splitting Lemma [7]. This result can be useful when designing algorithms for computing ρ and related formal invariants.
