Questions about Paph watering

[ElfOwlLover]

I am back with some more questions. I have two paphs that seem to be doing alright, and are potted in coarse bark. I wouldn't say that either look dehydrated, although I could be wrong. The one in the larger pot (at least 5-6 inches in diameter) had some sphagnum mixed in and, the one in the pot that is around 3 inches in diameter had a layer of sphagnum on top. I water every few days, or when they/the top layer of moss seems dry.

I checked the roots and while the one in the large pot had only one healthy root, it had a active growth on the tip. The only other root it had was on its way out when I checked a while ago, and was now dead. However the little one had a bunch of dead roots and was left with only two roots that were an inch or two long. I removed the sphagnum as I suspect that it was retaining too much moisture, and am wondering if I made the right call. I also am just questioning whether it is more likely that I under, or over-watered them. Neither look too bad by my standards, just want to prevent them from becoming worse due to my lack of knowledge.
Any input would be great!
