Stockman's BFF is a combination of a new technique for undetectable writing, and an approach to
presentation.
If you have mastered a technique for undetectable writing, Stockman's
thoughts on presentation, especially in front of a small group, are inventive and novel.
The technique side, however, is more challenging. When done as he describes, the hand position
for undetectable writing is, as I view it, not particularly natural, that is to say not how one
would normally hold the hands in that setting.
Perhaps more of a problem is the difficulty
of developing adequate competence in the technique so that the writing is both undetectable and
appears to be legible natural hand writing when shown to the audience. To become proficient
requires more than hours to days, or even days to weeks of practice. It will take weeks to months
of diligent practice to really become adept at the technique. This is not so much a criticism of
the effect per se as of the advertising that does not really make clear what is required to master
the effect, so that the buyer can make an informed choice.
