I think the plots for the D15 T and D9W are intermingled. In the new catalog that is. The D15 is shown as burning for 2.5 sec and the D9W only 1.5 sec, which is the reverse of what I believe the burn times are. Both motors are 20 N-s total impulse, so the areas under the respective curves should be about the same. As is, the plots make it look like the D15 has about twice the impulse of the D9. I think the previous catalog had the same error. I just finally took a look at the thrust curve that comes with the D15 reload to confirm it for my own self.
