<comments>Corrected 2026-09-23 from ThrustCurve.org simfile 5f4294d20002e9000000030c (user, RockSim).
Separated repeated timestamp(s): t=0 s (2 points moved to 0, 0.01 s). Each jump now takes at most 0.01 s instead of zero time; no thrust value changed.
Header Isp and massFrac were 0, which ThrustCurve now rejects; set from the header Itot, propWt and initWt, as in Contrail's other files.
