Sixtests on file #25 says that the half stroke was powerful - you overshot 
the parabola by quite a ways - RMS up to 44.7 nm, conic constant b is now 
-.577, undercorrected.  Try the following to get to my suggestion:

1) click "Target"
2) click b window, put -1 in the dialog box, OK (why did you put the -2.513 
in the input file? - handier would be to put -1 0)
3) uncheck R-fixed
4) click R window, then hit down arrow once (get fixed R = 2603.738)

Relative to this parabola, the center is very high, and makes the TDE look 
less threatening.  Then Tex says, p. 97, for "Center too flat, turned down 
edge" do "Method A, stroke II", "Method B, stroke II", or "Method C, stroke I".

Try one of these, but short spells to see what works,
