Yes, the thinner the edge the faster it will deform, but j-knives in general are more up keep. I believe Jeff said it best "A Ferrari requires more up keep than a Honda, isn't that part of the attraction?"
I couldn't give you a number if I tried. Personal perception plays such a huge roll it's impossible to give any concrete numbers. I keep most of my j-knives around 10dps, but I'm just a lowly home cook so edge retention and/or chipping don't concern me... as I enjoy sharpening and I have more than a few backups
The only real way to know is continue down the rabbit hole and give it a try.
