In previous post's discussion, as here, the comparison was AHD demosaicing followed up radius 1 unsharp mask final sharpening, for the bottom image.

Compared with Amaze demosaicing plus RL Deconvolution presharpening, in Raw Therapee. Followed by the same radius 1 unsharp mask final sharpening, all for the top image. The test photos are of a New Yorker magazine advertisement halftone image.

The unsharp mask of 1 is too much, especially for the top photo, at least. The RL Deconvolution sharpens all by itself. You may not need any further sharpening. But if it's already sharp and you insist on sharpening, try a .5 radius first. The top photo looks like it's buzzing a bit too much for my taste. But it is sharp.
