I.e., if the probability of a bit error is "p", a 7 bit pattern will be correct with the probability 1- p^7.  With the pseudo sync method, this number is 1-p^5+epsilon, where epsilon is very small, since we are not even looking at the individual start and stop bits.

Oops, bad typo.

The probability of correct reception in the above are (1-p)^7 and (1-p)^5.
