consecutive triples

[Frank]

Saturdays triplet 28,29,30 prompted me to take a look at consecutive triples (triplets) and see where we stand so far.

Of the 47 possible, I think there are six triplets still never been drawn in the first 6 balls:-

07,08,09
13,14,15
19,20,21
29,30,31
40,41,42
45,46,47

An average of 36 draws between triplets means this information may not help, and some triplets have been out more than once so we can't guarantee that the next one will be from this list. If only it were that simple.
Something to take into account when using another system maybe, to narrow things down ?
