    Does D segment or round segment produce more jump?

    Hello,

    I'm getting conflicted answers so thought I should ask on here,

    1. 'Round is more blended than D seg so there is less of a jump, with D seg there is more of a sudden introduction of the near'
    2. 'the larger the segment size the greater the jump, as there is more distance between the dividing line and the segment centre of a round segment there is a larger prismatic effect induced'

    Please confirm which of these answers are correct, I'd just like to be sure.

    Thank you!
