Hyperfertile trait is making it a bit too much

[Namikan]

Hello all, I have fertility sets to boosted and cycle length sets to normal-to-long, and my female sim experiences an average fertility rating from 6% to 80% during 6 days at each of her cycles.

She's usually assured to get pregnant on her next ovulation if she's not on the pill, and often it's sets of twins.

Since the last update of WW added the hyperfertile trait, I thought it would be neat to give it to her and change my fertility rate setting to realistic, in order to reduce fertility in general and reflect the fact that she is most fertile than average.

But with the trait she keeps being at 54% fertile on her first fertile day to more that 100% on her the last 3 fertile days.

I tried changing the fertility setting to every options, from low to extreme, and the numbers never change.

Don't know if that's an issue or intended to work that way? It just seems a bit of a shame to me that it's that extreme and doesn't adapt depending on the general fertility rate setting...
