Source: The first geometry remains: edges 2 mm and 4 mm, supplied layers 1 mm at 4 min. For this supplied interval, the layer starts at depth d_start = 0 mm when t_start = 0 min. Average front speed = Δdepth/Δtime = (d_end − d_start)/(t_end − t_start). This is the model's interval average, not a constant future speed, intrinsic diffusion coefficient or molecular flux. Separate endpoint lists remain G: 80, 90, 100 s; H: 90, 100, 110 s. Additional notes state common temperature and standardised stirring, but endpoint time was judged using resolution 10 s. The notes and numbers are authored conceptual material, not measurements.
Task: Keep or revise the endpoint claim with reasons. Explain what the newly common conditions resolve and why overlapping lists, three values and coarse resolution still limit confidence. Propose a better recorded endpoint measure or resolution and independent evidence. Give the unchanged number comparison and one unchanged geometric fact. Equal temperature/stirring does not remove every source of uncertainty or prove significance.
