You are right that testing for fixed depth for that purpose is simpler but
EPD2WB has not an option to test for fixed depth and I did not care to develop a
special program to analyze epd files after the existence of EPD2WB

It is easy for me to change the maximal depth
but the problem is that for programs that support analysis(movei of today)
EPD2WB can be slower than necessary because I use it by fixed time and if I give
it time that is enough to get depth 11 for all positions then it means that most
of the time the program does nothing.

Maybe in order to get the same depth for all positions it is better to cheat
EPD2WB and tell it that movei does not support analysis.
I can do it by changing analyze=1 to analyze=0 in the following line

printf("feature setboard=1 draw=0 analyze=1 ping=1 done=1\n");

The problem is that in that case movei may play too early based on my experience
because EPD2WB does not support long time control correctly.
