This was a problem for me making gun tables.
There is a very large difference between the French data on the performance of the 47mm/L53 and the German data. The penetration according to France is more than 40% higher than the German evaluation. For example according to the French Ministry of Defense the shot should penetrate 89mm @ 0° @ 500m. But the German data gives it only 50mm @ 30° @ 500m.

We have an even more detailed post here at #3.

It is interesting that it looks like the striking velocity can be backwards calculated using the Demarre formula from the French data table on that post.
