>Yes, we all use the same methodology.

I am not so sure.

You told me long ago that you multiply by 50.000 and I said we multiply by
10.000.

I haven`t been able to read both Caldwell and Fries papers, but after the
seminar by Gabriel Sarlo from Argentina, I understood that if the sample is
not homogenous in the Neubauer chamber you count only 5 Thomas reticules and
multiply by 50.000, but if the sample is homogeneous you count all of them
and multiply by 10.000.

I am waiting for the papers to confirm the above. Any one have them?.
