Vtracs is just way of combining few digits together(most vtracs group 2 in each and that makes total numbers as 5 instead of 10) and track them as one. So you shrink and expand your past draws and the same goes for combos, pairs and prediction. It seems to reduce the number of items - digit, pair,combo that you at a time when compared to 10 digits. But the original odds remain same.
1 0,5
2 1,6
3 2,7
4 3,8
5 4,9
These are most common grouping used by most lottery players. This is more of a mirror and low/high pairing.
There are many other grouping that can be used : flips, sequential, odd /even, etc., and custom groupings.
Examples:
01,23,45,67,89 can be tracked as v 1,2,3,4,5
09,18,27,36,45 can be tracked as v 1,2,3,4,5
Once grouped, then every possible digit based tracking can be used for vtracs

vtracs box/straight positional digits
vtracs box/straight positional pairs
