I believe I have reached the limit of how dry I can make this pen. It's only too wet at first or after sitting for for a while, otherwise it's quite dry.
My Lamys, Pelikan, and Twsbis did that, if I understand you correctly. They would start off really wet and then gradually get drier and drier and drier, and sometimes completely dry up mid sentence even though they were mostly/partly full of ink. A pen shouldn't be like that. For me one shouldn't have to resort to hacks to get to write hassle free.
I still think the solution that I suggested will make it write as it should. I did the same thing on a Pilot FA nib the other day. Although it didn't exhibit the behaviours mentioned above, it did randomly skip even though it was massively wet.
The reason why the solution of crossing the tines works is that the ink flow was too wet resulting in it quickly becoming exhausted, causing it to either skip(in my case, because the FA is a very soft nib so the ink supply would suddenly cut off) or (in your case) to gradually become drier.
I suspect something similar is happening with your pen, and that it will encourage the ink flow to be more regulated.
To visualise it, picture 2 rivers: a fast flowing narrow river and a slower moving wider river. Whereas the fast flowing river is self dredging and therefore will produce a consistent flow, the wider river will silt up and lay deposits so that it can't flow as freely as it once did. The gap between the tines on a pen is this river.
If it's not something that you want to do, it's worth bearing in mind as a last resort.
You mention that it's your favourite pen, so does that mean that it's only recently started behaving like that, or has it always been that way?
