artillery delay for small mortars

[Mario_Fr]

For scenarios you are right. But I`m speaking of campaign-play.
I just had a look at the Americans, who in May 44 have a base experience of 65. I bought some 60mm mortars and even a Ranger FO (+10 experience). Artillery delay is between 2.3 and 3.3. So bombardment starts between turn 4 and 5. One turn is supposed to represent some minutes, isn`t it? So what, they are reading the manual in between?
I mean, maybe I`m wrong, I never served in an army nor ever shot a mortar but I still think that delay should be not more than 1.2 even for the worst team and maybe 0.4 for experienced crews (more than 70 base experience).
