I'm not aware of any figure ranges or any previous written material. So I assume not.
I would be curious about the Chinese army especially. I assume that the Japanese are an earlier version of the 1905 crew with earlier generation firearms and artillery. But I have no idea about the Chinese. As recently as the 2nd Opium War in 1860, they were using bows and matchlock muskets.
The Qing modernised parts of their army after the 2nd Opium War owing to the ongoing Taiping conflict and subsequent campaigns against Muslim breakaway states in Yunnan, Gansu, Shaanxi, and what is now Xinjiang; the Huai Army, which bore the brunt of the fighting in 1894-5, was one such modernised army equipped mostly with breechloaders and even magazine rifles in many units. However, the Huai Army was augmented with a substantial number of hastily-raised levies, often with nothing better than spears. So equipment-wise, the Qing forces deployed to Korea ran a pretty wide gamut, with some units having a leg up over the Japanese (who were at this point using the single-shot Murata breechloader), many having parity, and many being pretty behind.
