tilhistogram contains the percentual quantities of each slot in the til.
Ex.
Suppose a jogotil(5,6) happens to be 02310.
Suppose further that the 5 quintils are unbalanced, so that til 02211,
focusing on the right-most one, does not make sense for there is no dozen at til 4 (the last one),
in other words, the last til-digit must always be 0 anyway.
Thus the tilhistogram is a way to "sense" a bit this discrepancy in the frequencies.
