How to avoid inner parity? Edit: I found that using OPA, tracking pieces under 12 seconds is possible to not get parity. But I won’t use OPA. Too complicated for me.
I think you can do so by doing this alg 3L' U2 3L' U2 F2 3L' F2 3R U2 3R' U2 3L2 which is just a swap, when used correctly should case the cube to no longer have inner parity. but tbh in not a big brain big cuber so I think asking someone else would be wise.
