Table 5.

Out by 10 probabilities for selected values of e and k. The table shows the probabilities of out by 10 errors blocked by syntactic checking, generated from an exhaustive analysis of errors when keying target numbers in the range 0 • 01–99 • 99 in steps of 0 • 01. The table shows clearly that even with very conservative assumptions, over 30% of out by 10 errors are blocked.
