We're similar, our yellow tees are theoretically 0.4 of a shot easier to par than the whites, most disgaree with that and think the yellows are harder.
To go further, at my home club, par 72, SSS 70, off 6 I was effectively 4 as folks always think of par as the number. At Newmacher as an eg, par 72, SSS 74, now I'm off an effective 8. To play to my handicap, the target was already moved, now instead of the target moving, I get more or less shots to start with. It intuitively feels wrong.
Has your CR changed from the old SSS? Have the yellows always been harder than the whites? What are the lengths of both?
Your Index is computed from the de-sloped CR not par.
