"mostly" -- yup.
The masks always take 9 chars per 32 bits of the full mask size (whether zeros or ones.)
The lists can take up to approx one to three chars per bit, for the worst case lists of every other bit, depending on the log base 10 of the highest included bit.
Consider for example:
97,99,101,103,105,107,109,111,113,115,117,119,121,123,125,127
vs.
AAAAAAAA,00000000,00000000,00000000
which, if I did my math right, are the same value.
