I tried it on my program. Very few arithmetic, most of it with annotation. 10%. On an arithmetic benchmark, it would be in te *10/*20 range. This 10% is orthogonal to what profiling shows. It just makes a lot of little improvements spread everywhere. That's why it couldn't be solved with annotation.
