Can you and if not can HPS look at changing it?

I´m no mathematician or especially skilled in statistics, but I made some quick tests. I made a test scenario using Moscow 41, and turned 50 hexes of Moscow city into RUBBLE. I placed 50 engineer units in those hexes, all identical with 500 men and morale C. I placed another identical 50 engineer units outside the city in various terrain. The PDT gives a Digging-In chance of 10%, which in turn affects Clearing Rubble and Mine Laying, as we can see in the Manual as Glenn said above.

In the first test I had the city engineers Clear Rubble and the others Digging-In. The Diggers were all complete in 8 turns, that is they had all built improved and then trench. In the first turn all 50 succeeded, a freak result I suppose. Then the rate slowed, 23->17->6->3, but all except one unit were complete in 5 turns. I then remembered that engineers dig-in twice as fast so that part of the test is not so useful, as results should be halved.
The 50 Rubble clearers worked hard for 17 turns, averaging 1.3 cleared hexes per turn. The highest was 3 in one turn (three instances), the lowest 0 (four instances). After 17 turns 22 hexes had been cleared. The average clearing success in percent was 3.3.

A made a second test, where the 50 engineers outside Moscow were laying Mines instead, while the Rubble clearers kept on their work. In 17 turns 27 hexes were cleared of RUBBLE and 28 hexes were laid with mines. That is roughly 1.6 hexes per turn. Per turn that is 4% if I have calculated correctly, so somewhat less than the 5% that we could expect according to the manual. This test did had several high freak results that could push the numbers up, giving a faulty result. Or the first test is faulty.

So I have perhaps proven myself wrong, the test (admittedly limited) point to something lower than what the manual says but not by much. But I still have the feeling that Clearing Rubble is less than slower than half the Digging-In probability.

(and yes, I felt a bit like Stalin doing this, forcing 50 000 Red Army engineers to work day and night for the greater good :) )
