The possibility of yet to be revealed marl and sand filled magazines, especially in the higher levels, does imho suggest a total even less than 2 million.

These blocks were not 'transported' to their level in finished form. The final fitting would have created the very fill I suggest.

perhaps as high a factor of 10%.

The more I consider the project..the easier it becomes

or rather really really F-ing hard instead of really really really F-ing hard.
