VTRAC   =    Digits

   1            0 and 5

   2            1 and 6

   3            2 and 7

   4            3 and 8

   5            4 and 9

-------------- So:

1 = 0 - 9

2 = 1 - 8

3 = 2 - 7

4 = 3 - 6

5 = 4 - 5

-------------

1 = 1-0

2 = 2-9

3 = 3-8

4 = 4-7

5 = 5-6

-----------

1 = 1-2

2 = 3-4

3 = 5-6

4 = 7-8

5 = 9-0

-------------

1 = 0-1

2 = 2-3

3 = 4-5

4 = 6-7

5 = 8-9

Those are the more or less "Logical" variations, but there could be other ones not so "Logical"

These are just to show that there could be other methods that could also be based on 5 digits that also equal 2 digits each.

Which of them or other possible ones would I use? I don't know, maybe "Regular" VTRACs as there is no software for any of the alternatives.

I won't have a chance to look into VTRACs at all for a few days to 1 or 2 weeks, but this time I really will, because I will see if it is possible for me to use them in some way.
