# In Google's Quantum Supremacy experiment, what if we use $\theta=45°$ for two-qubit $f_{sim}$ gates?

In Google's Quantum Supremacy experiment, they use $$f_{sim}$$(fermionic-simulation) gates with $$\theta=90°$$ and $$\phi=30°$$ as their two-qubit gates. What if we use $$\theta=45°$$ for the two-qubit $$f_{sim}$$ gates? What will it do to the experiment's complexity?
