Subject: extension depth

Hi

I just wondered, in Shredder it seems that there is a limit to the extension
depth, in example it shows 10/20 and i interpret the first number as the main
depth and the last as the extension depth( i may be totally wrong, it wouldnt be
the first time !!! :) )

Now the question is : Why is the extension depth always 2x the main depth ??

Is there some studies that show some connection between the extension depth and
the main depth ?

Or is it just a coincedence ( seems a little far fetched )
Or is it just a rule, so the search tree will not explode to much ? ( more
likely )
Or is it just a decision by the Stefan Mayer-Kahlen ( i think this is most
likely )

I mean why not 2.5x main depth or 1.7x main depth etc.

With regards
Kim
