Hi, I'm also really looking forward to reading this!!!
I have to admit I also fell into that camp of disappointed neophytes on reading the description in The Mind & Magic of David Berglas. Giving David Britland his due on a lucid mammoth of a book, I think I'd naievely set myself up to read complete step-by-step instructions on creating "the perfect effect". However, I was interested to read, "it's all in there if you look hard enough" and that prompted me to re-read that last bit of the book.
I might have misinterpretted this but it seems that Berglas does indeed have a general strategy to create the perfect effect, as Britland refers to "good cards" being named in the course of a larger routine. From what I understand from the bit on the selection of number and from hearing other people describe his performance, I imagine that 'good cards' are cards which fall closest to either end of the stack, as "a number" can then be named (please forgive me for trying to be both cryptic and explicit) which is likely to be very close to the position of these cards on considering the pack three dimensionally. The bit on having the spectator re-order the cards (you know what I mean) would suggest that you could account for all four suits within this range of selection, as the inside becomes outside. (crikey, this is sounding alot more complicated than it is!)
This got me thinking, as one choice indirectly affects the other. If we forget the suit of the named card (because this becomes irrelevant due to the afore-alluded-to subtelty) and think of it as a choice of two numbers, the second choice is naturally influenced by the first. For example, if I named the number 7, my second choice would probably be 3 and, in fact, any two choices are likely to hover around either end of the range of selection, which is elegantly mirrored by the stack; so the perfect effect (or one that is very similar) becomes within reach of being 'surefire' on considering a few of the other subtleties, without seeming to limit either choice in any way.
Having a set-up that will give you the best chance of hitting without any intervention seems to require more ingenuigty and experience than I can ever muster (and I appreciate I'm a deluded skintflint for imagining I can purchase said qualities for $100) so, what I'm particularly interested in is the specific stack and outs Berglas uses for numbers to achieve this (such as the example given in Mind & Magic). Unless I'm completely wrong, I believe this would give most of us muggles a chance to create this effect, albeit perhaps not as splendidly as Mr Berglas.
Trying my best to sound like I'm not fishing: will this be in your book? ;)
