If there was more than lot to lot variation, they would be calling the new powder 2399 or 2401, not 2400.

Excellent point! I hear the same said about old / new Unique.
If the powder's performance changed enough to make the pre-change data obsolete they would just re-issue it under a new name.
On another point, H110 and Winchester 296 were/are considered to be the same powder using identical data.
In the 80's I used both and the powders were physically different.
The 296 looked like it does now, dark, small balls. The H110 was a bright silvery gray and with much finer grains.
Performance was similar, but not identical in grain-for-grain loads.
