Hindu force origins...

[Lord Magic]

Okay...so I saw that in the Royal, they describe a different Hindu force than what's usually used.
So just wondering...
If the most basic and kinda one of the best books on card magic not even mention the popularly used Hindu force, definitely it is not the invention of some great cardist? That is what my naive mind thinks tho.
So the question is, who started this more used version of the Hindu force? Was it something random done by magicians Lille many of today's sleights are? A small addition to the original work made by no one in particular?

REF:- If you dunno the Hindu force taught by RRTCM, I don't think I will be able to help even if I want, just know it forces the top card. And the 'popularly used' Hindu force I am talking about is the one that forces the bottom card.
So...origin?

From the research I have done, although the Hindu Shuffle Force has been widely published, the creator is unknown. At least according to Dennis Behr, a well-respected card magician who has put together a huge database called "Conjuring Archive." See http://www.conjuringarchive.com/list/category/1163

According to the website, conjuringcredits.com, the Hindu Shuffle force "is described in R.P.'s Ein Spiel Karten, 1853, p. 43 of the Pieper translation" but it was done "with a variant overhand shuffle, with the deck turned on end." See http://www.conjuringcredits.com/doku.php?id=cards:hindu_shuffle_force
From that description ("deck turned on end") it sounds to me like the deck would be held in a horizontal rather than the usual vertical position. (I actually tried this and it felt and looked awkward). In any event, since we only know that it was described by "R.P" (whoever that was) in the above-mentioned publication, that does little, if anything, to enlighten us as to who was the creator of either the Hindu Shuffle Force or any possible predecessor of the force.

Unless someone has any other more definitive information, it looks like it will remain a mystery.
