These are also my concerns, as enumerated in my above posts. I asked Oliver, an expert on the period, the same questions regarding the Prussian Army.
I became interested in this, among other topics, a number of years ago. I then started a Russian database to help me study what actually took place during the period. Not unexpectedly, there is inconsistency. As stated above, I am still without a definitive answer, but still searching!
I will keep you posted with any discoveries.
