News on the Perfectly Suggestible file

While I am postponing my first use of the Perfectly Suggestible file until I've finished work on a few other experiments, I did inform others on #pony_hypno.  I've gotten 4 reports back so far.  In each case, I asked that they listen to the Perfectly Suggestible file and then a file that they had already heard before, so that they could compare

(Tester asked to remain anonymous): Tested: Perfectly Suggestible + Fluttershy (Genderbent Original)
Did not achieve a proper trance, and had trouble will dizziness after first file.  Second file worked well without  a proper trance, however.  Repeated second file.
Result: Noticeable personality shift, physical change, Initially unnoticed voice change.
By the end of the day, had mastered the voice change.  Could switch into and out of at will.

Twilit_Sporkel: Tested: Perfectly Suggestible +Anthro Pegasus
Slight headache from the 7+-2 induction. After second track, best results with that file.  Rated 9/10, intends to repeat for the next few nights
Result: Tail, individually mobile phantom wings

EDIT: Two others testers reported back.  one was generally positive, if unspecific, while the other saw no change.

EDIT: Another has reported in.  No negative effects, slightly better results.


Summary:
Positive effects: increased suceptibility as promised for most users.
Negative effects: potential for headache, and dizzyness
