I am just rambling on here as I do not track v-trac numbers.I was just looking at the v-trac no match looking for comparisons. I used my system w/key pairs compared to the v-trac no match.
As I see it.
The 234 v-trac should be the most frequently drawn.[ I would think very frequently]
The 134 & 235 are next in line.
The 124-135 & 245 should be next.

Any v-trac users to give me feedback.
