Question on Reinforcements

[LEGXXIIPRPF]

The probability doesn't increase with each failed check. I'm not sure if there's an option in the code somewhere to make it do so, but normally it doesn't.

To make sure at least part of a formation arrives, scenario designers sometimes choose to let reinforcements arrive with a check at brigade/regiment level if a HQ exists on that level. 

That also reduces the variability in available forces between games where no Daily trigger units arrive and games where most or all units arrive.

Thanks a lot, ComradeP!!
