We use coupling ideas introduced in \citelevine2018long to show that an IDLA process on a cylinder graph G× ℤ forgets a typical initial profile in O( N√(τN) (log N)2 ) steps for large N, where N is the size of the base graph G, and τN is the total variation mixing time of a simple random walk on G. The main new ingredient is a maximal fluctuations bound for IDLA on G× ℤ which only relies on the mixing properties of the base graph G and the Abelian property.
