1C and 2C degradation

[tsiz]

All,

After the addition of 3C, my 1C and 2C get degraded from both accessibility and retainability perspective.

I understand from a retainability one..where traffic has decreased but the drops have reduced by a little leading to bad retainability. But from the accessibility one..I am not able to understand. My 3C is an OBIF solution with E///.
