I re-checked my records. I developed a roll of Neopan 400 two days before the TMY2 rolls, and one day after. Both Neopan rolls came out fine. Here's the graph of the day-after Neopan roll:

I've improved my methods to eliminate some wobbles in earlier graphs. Here's a graph of batch 0166 of TMY2:

This one has wobbles, but you can see that it's roughly a straight line, unlike the latest TMY2 (batch 0167).

What do you think of these graphs I've been posting lately? Do they look like what you'd expect?
