    Looks the same as doubling your first three digits and moving
    them over four place values (what multiplying by "80*25"
    accomplishes i.e. x "20,000") to be able to insert the last
    four phone number digits (albeit doubled). Of course this is
    partly hidden by the "mysterious" increase of 250 (1 x 250),
    which is later removed, and finally removing the doubling
