    It says .75 which should be 9 month or of a year.

    The regular maintenance interval for MV SWGR is 24 months.
    0.75 x 24 = 18 (months).
    Please refer to NETAWORLD brochure Summer 20111 on the Quiz questions.

    It should not be such a mystery in the NETA MTS/ATS then, they should spell that out. Why be so vague? Everyone does not read the NETA World quizzes, but everyone does refer to the NETA MTS/ATS.

    I am proven wrong, the attached part is in the NETA MTS, right below the multipliers. Thank you.
