There are two complex issues here. 1. The theoretical justification of FP differences for various nations.
Establishing the constant values of some variables like charge-size, accuracy, rate of fire, and supply ability mentioned above is not easy to say at least. For example, rate of fire and supply availability (and in occasionally quality of ammo) were never the same and in one’s turn dependant on other variables –e.g. tactical situation, personal preferences, weather, speed of manoeuvring and changing positions, timing, condition of the ground, the age of the barrels (the section of the barrel) etc. Trying to generalise all these variables is not realistic.
I am attaching a few tables from Nafziger to facilitate the discussion. At a number of points, these tables contradict the information found in other sources which complicates the issue even further. Also, as noted in the book, Nafziger research was based on a number of assumptions due to lack of information and especially the lack of reliable scientific tests. Also, occasionally the data available was from 1820s and even as late as 1860s.
In 1904, Colonel Nylus, the inspector of Artillery Academy and the author of a few textbooks on artillery undertook a gigantic research with a goal of establishing the effectiveness of similar guns across various nations from Napoelonic era. He examined the following sources:

His conclusion can be found on page 42 of the H&R Main PDF.
Of course we are all welcome to try to come up with something better than colonel Nylus, but most people would agree that it is hard to be optimistic about the credibility of such findings. Most likely to arrive at the justified and credible findings, it will require an international team of highly specialized professionals in the fields of military history, artillery, physics, linguistics and mathematics, along with ability to conduct laboratory testing and forensic investigations. Even in this case, such team would have to operate under a number of assumptions, in particular regarding the availability of ammo and actual, in battle rate-of –fire which was dependent on the tactical situations and specific orders of the field commanders.
2. In-game application of FP.
Even assuming the hypothetical scenario that for example an Austrian 3-lbr was superior to Frenhc 3-lbr we face another complex issue. How do you measure the difference and apply it correctly to PDT FP table?
Also, artillery FP changes should take into account the minutes per turn and in-game movement speed factors. For example, in the game, it might take 3 turns for infantry to approach the guns, which is translated to 30 min (less hypothetical command delay for infantry). How do you adjust FP to make it more historical taking into account that in-game FP and opportunity to shell the enemy does not necessarily reflect the number of volleys the battery could fire ?
Furthermore:
“The only statistics available on the actual casualties that were ever inflicted on an attacking unit come from the German historian Muller and are given in Table 88. He served in the King's German Legion and assessed the numbers of casualties inflicted by a 6-pdr during such an attack. In addition, he used a higher rate of fire in his calculations. The average was two round shot per minute or three canister, but Muller seems to believe that the artillerists could reach a rate of eight rounds per minute when being charged. Unfortunately, he does not indicate the type of formation being fired upon, which would make a considerable difference in the number of casualties likely to be inflicted. Inasmuch as cavalry generally operated in line it must be as-sumed that the figures for cavalry casualties are based on firing on such a formation. With that assumption, one should also assume that he was consistent in his assess-ments and that the infantry were also formed in line.” (Nafziger, Imperial Bayonets, p 271)
As of today, there are no comparative findings on causalities inflicted by artillery, hence how do we know how to measure the relative effectives of our FP changes across different nations and especially at different ranges?
Finnally, the HPS FP scale generally ranges from 16 FP to 1 FP. But it is likely that, the difference in FP of guns used by various nations would be not that material and the current FP scale (from 16 to 1) is not detailed enough to model the possible damage which can be inflicted by guns used by various nations esspecially at different ranges. A more gradual and detailed FP curve is need for this (for example like 32 FP to 1 FP) but as of now it is not how the engine is designed.
