We define a finite size renormalization scheme for $\phi^4$ theory which inthe thermodynamic limit reduces to the standard scheme used in the brokenphase. We use it to re-investigate the question of triviality for the fourdimensional infinite bare coupling (Ising) limit. The relevant observables allrely on two-point functions and are very suitable for a precise estimation withthe worm algorithm. This contribution updates an earlier publication byanalysing a much larger dataset.
