Infantry Thoughness values ?

[Nightblade]

After making a short battle with the computer, using 60% as troop thoughness for both sides, i am now puzzled.

Because it does not seemed different than with the usual 100% and 80% i was playing before.

So is this setting really doing something ? is it broken ? or was it just this test battle in which both the computer and myself were unlucky with the hits/casualties rolls (as it is always possible) ?

Have someone noticed higher casualties (at equal level of squad experience of course) while playing with a low troop thoughness ? if yes , with what percentage ?
