Entropy calculations wrong?

[mvevitsis]

If I'm not mistaken the correct formula is
E = L × log2(R)
A 16 character password using lower case, upper case, digits, and ASCII symbols should have a range of 94, so:
E = 16 x log2(94)
E = 16 x 6.55
E = 104.8

However this app reports such a password as having an entropy of 72.45

I am using the library GoSimpleLLC/nbvcxz which is based on dropbox/zxcvbn, maybe you could take a look there.
