Done that, Dave. I did a series of tests. Each time I played as Allies and gave orders to the CCA 7 Base, in Manhay, to get out of there to defend near the SEP to the north, out of harms way. What I recall clearly from playing this scenario, say 2 years ago (roughly) was that the CCA7 Base was always caught by the Axis and killed (exactly as happened historically).
So I set the initial orders delay (IOD) for Allies to;
0 and 120 The order reached the base at scenario start, which is 9pm
100 and 120 The order reached the base at 21.16
150 and 120 The order reached the base at 21.26
200 and 120 The order reached the base at 21.33
300 and 120 The order reached the base at 21.51
400 and 120. The order reached the base at 22.07
When you change the IOD in scenmaker, save and exit, it crashes to desktop. However, the auto generated entry in the briefing of the scenario, when you start it in the game, shows the value for the IOD that you have set, despite the crash. When you set the IOD value to 150, however, even though the auto-generated line in the briefing shows 150 when you open scenmaker again after running the scenario, scenmaker shows the IOD as 100. This only happens for the 150 value (that it reverts to 100 when you re-open it in scenmaker).
Something going on with that CTD no doubt. But, do the values above look right for the delay period? They are none of them sufficient to fix CCA 7 in place until the AI Axis attacks. To get that I had to set a value of 600 and 120 and only then did the AI Axis manage to get to CCA 7 and engage it before the order to shift out got to it. In fact, to be safe 700 would roughly replicate how this scenario used to play out around 2 years ago, and how it happened historically. I'm sure it wasn't set to 700 and 120 two years ago though!!!! So something has changed. As you see from the earlier post, if I play as Axis I can clear out the roadblocks and get to the base before it can flee with just one order.
