Generals had been massing their artillery for about 100 years before the French Revolutionary and Napoleonic periods. So that question is moot.
Russian military education, especially technical education, was behind that of Britain, France, and Austria. If you don't have a solid technical background, and the artillery education is poor, the technical skill of the artillery officers will be poor. Hence, there will be facets of the artillery arm, gunnery in particular, that are not up to par, so to speak. Boulart is one of the French artillery officers that remarks on the inaccuracy of Russian artillery fire.
Other examples are at Friedland when the French artillery batteries on the west bank of the Alle knocked out the Russian batteries on the east bank during the fighting. Another is Borodino where the outnumbered French artillery dominated the field. The professional skill of the French artilley arm is well-known during the period and is mentioned by historians from time to time. Then you have the compliment of the British along the Niagara frontier in 1814 remarking on the skill and accuracy of the American artillery companies during the fighting that they thought the American artillery was French.
