Division, not multiplication. So logb(x) = ln(x)/ln(b). Close John. log10(x) = ln(x)/ln(10). Division, not multiplication. So logb(x) = ln(x)/ln(b).

Also, when you say that the number of bugs discovered is "directly proportional" to the number of users, you are stating that NumberOfBugs = NumberOfUsers*ConstantOfProportionality. What you mean to say is, "the number of bugs discovered is proportional to the logarithm of the number of users".
