Sorry, but also your 00:45 is misleading! ;-)

It depends on what settings you´ve made _before_ starting the automatic mode -
if you look at the position, it´s clear that ´ChecksOnly´ and ´Threats´ can
be switched OFF, and if you set ´SearchOrder=XPK´ (which is faster mostly),
then you get the following:

ChestUCI Ver.4.0:

Kh2 16.Rh7#
1. Solution  (Mate in 16)

So with a bit clever setting you will indeed get 00:00 -
even on my slow Celeron/400! :-)
