The only thing that is scenario specific is the parameter data that is being used. Check and see what the Digging In percentage is. For Moscow '41 I think it is always 10%. So, each turn there is a 1 in 20 chance of clearing RUBBLE and that chance is independent of the previous chances. You can easily go for more than 20 turns without being lucky. Simple as that. I do not see anything 'extreme' about your luck. And anyway sometimes you can be very unlucky.
