Great curves! Finally something that proves what I've always thought -- that TMX has more of shoulder than TMY2. Most of the internet folklore says they're the same.

That's what I found as well when formulating my own developer. Here's an example:
To avoid compressing highlights, TMX needs to be exposed accurately when developed in developers that yield these long shoulders (and not all developers do this).
Also, notice that the curve for TMY2 bends *upward* a little at about -1.4 log lux-sec in the following graph:
This also agrees with the curve at step 18 in this graph: http://www.fotoimport.no/filmtest/fkxtol.html
