Constructing a Balanced Defence vs CO 3bet

So I'm trying to construct a balanced defence range when we open in MP to 3bb and get 3bet by the CO to 9bb.

Say we open a standard MP range of roughly 206 combos and our MDF in this situation is approx 45% (could be wrong) this means we should defend roughly 90 combos.

How the hell do we build a balanced defence range including 4bet call, 4bet fold and flatting sub ranges with only 90 combos?

I work out that we need a bluff:value ratio of 3:1 since when V shoves (100bbs effective) our MDF= 25% (again my math could be completely wrong here).

If my math is correct here I just don't understand how we can build a complete range with so little combos, the range I have built is:

4bet/stack off: AA, KK (12 combos) 4bet/fold: KQo, KQs, AJs, A2-A5s (36 combos) flat: AQo, AKo, AKs, AQs, QQ, JJ (44 combos)

This gives a total of 92 combos which seems fine according to my maths but feels so nitty. Any help would be appreciated

With your MDF calcs I think you're assuming villain has 0 equity when called which is incorrect.
Looking at your stuff quickly, you have way too many 4b/f (I use A5s-A2s only) and are flatting far too tight and using the wrong hands to do so. I'd fold AQo, but flat ATs/KJs/QJs+/QQ-88, others would advocate wider maybe with 77/JTs/T9s. It's also dependent on sizing/your edge/stack depth.

That should help get your % up, also remember other players can help defend that MDF by 4Bing or cold calling.
