I understood Bob's line of thinking, and did the exercise for entering against a five point board. The number of rolls needed to enter x checkers against a five point board are as follows (using 4 decimal places instead of working with increasingly complex fractions):

x=1 -> NR = 3.2727 (which you knew already)

x=2 -> NR = 6.2479

x=3 -> NR = 9.2500

x=4 -> NR = 12.2495

x=5 -> NR = 15.2493

Seems like the number of rolls increases with 3 for every extra checker.
