But it holds also for these data that both programs may mean something
Depth of deepest line does not tell you how much the programs extend on average.
So Fritz may have found one line that goes 51 ply deep, yet its average
selective depth may be something like 25.
OTOH, Hiarcs might show 12/38 at the same time, but have an average selective
depth of 30. We just don't know that as the engines don't display this info.
