I have super powers myself I can see into the future.
There will come a time when reasons that the super powers didn't materialise will need to be created.
They'd better be better than MUs out ethics and Marcab. People will start to question the lack of product. No Clears, OTs who need NOTS, OTs covered in BTs, and now no super powers. ''The only thing we can be upbraided for is no result.'' Good luck Davey.
These "drills" are based on early 50's perception routines, which themselves are simple cognitive exercises. Do you remember the book " Self Analysis" ?
A bit of meditation and presence drills will recover far more of one's perceptions than spending tens of thousands in the SP building. After all, it is nothing more than Hubbard's mocked up Implant Station
