The large batteries, given the amount of smoke produced, would probably indicate un aimed fire, so large scale harrasment fire. The large battery at Wagram. it filled a gap in the French line and bought time for Napoleon and Macdonald. But it did not really deliver a knock out blow to the austrians ala Friedland for the Russians. It just sat their firing in the hope of hitting somthing in front of it.
The guard artillery at Dresden did carryout a similar action to Senarmont ay Friedland, but all the ground won by the advance was given back on Napoleons order, but the charign of Griois. At Lutzen, the battery sat their, the same at waterloo, leipzig. So the friedland, perhaps Ocana (not sure of spelling) artillery charges seems to have been a one off in terms of effect. Hardly artillery being a potent offensive weapon. Grouping guns in a single location and firing harrasment fire reminds me of 17th century and early 18th century battles where the guns sat and fired and a battle was more a siege than a flowing fluid action.
Also the point i was making that these large batteries count for a very small percent of total actions where artillery was employed by the French. The tactic seems to have been limited to Senarmont, Drouot, Griois and Lallemand, plus Napoleon. It is also notable that for the later massed batteries, these were made up fom the guard artillery. So rather than being common practice for the army as a whole, the guard artillery from 1812 were used as the material to form the large batteries rather than the line and corps artillery.
