Yes, although in my example, it's going from zero to -0.866. But the point is, in CMIF, once the duration of the acceleration gets fairly small, further reductions in the duration (with accompanying increases in the magnitude of the acceleration that keep the area under the curve constant) have negligible effect, and the age increase of the distant person quickly approaches a finite limit. That's what makes instantaneous velocity changes in CMIF so useful and simplifying. But in the "EPVGTD" simultaneity method, the age of the distant person doesn't approach a limit as the acceleration duration is decreased ... the distant person's age goes to infinity. That is an absurd result, and (in my opinion) it casts doubt on the validity of the gravitational time dilation equation.
