> But improving geometric mean would require improving all queries.
No. Improving the geometric mean only requires reducing the product of their execution times. So if you can make the two 1 ms queries execute in 0.5 ms at the expense of the two 1000 ms queries taking 1800 ms each then that’s an improvement in terms of geometric mean.
So… kind of QED. The geometric mean is not easy to reason about.
