All fine, you already fixed the bug, thanks! :)

The perceived "weirdness" was by design.

The upper percentage is only indicating the current search-span, not the sum of all already searched nodes.

That's how the numbers here have to be interpreted:

4.01% + 7.80% + 88.18% == 100%

(modulo rounding error)

It was always like this, so no reason to complain! =)
