One can use other number variants than the three card variant of the Camoin Method.
The 5 card variant:
The 5 card variant for example, has only a few differences from the 3 card variant. The energy is relatively similar.
This variant simply allows one to differentiate between the recent past and the less recent past, in the same way with the near and not so near future, represented respectively by the first, second, fourth and and fifth cards. The third card represents the present.
But in the end this method does not add much of value, because in the three card variant, it is the Spirit of Tarot itself no matter whether three or four or five cards end up on the first row.
The 7 card variant:
The 7 card variant is also based on a sacred number and not on a mundane number. The energy which emanates from it is pleasant. But because of the large number of cards which are on the table, interpretation can be very difficult.
