46% isn't a cap, it's just a result of how multiplicative stacking works.

If you penetrate 40% of their armor, then penetrate 10% of what's left, you're only penetrating 10% of 60%, so it translates to 46% penetration in total. Luckily, because of how multiplication works, it comes out to 46% regardless of which order the penetrations occur.

So, in the case of, you'd be penetrating 15% of what's left: 46% penetration leaves 54% to be penetrated, and 15% of that is 8.1%. 8.14654.1% penetration in total.

I hope this has helped you understand. If you need any further explanation, let me know.
