Episode-wise duration vs. MVT for the ME spike (G1, red star) and EE (G2, orange star) components. The reference Type I (gray) and Type II (cyan) GRB populations are taken from V. Z. Golkhou et al. (2015). Both components lie in the long-GRB (Type II) region, while the EE typically has a longer MVT, indicating smoother temporal structure.
