Over the years I have been an on-again/off-again LoTW participant. Really my uploading logs is more about helping others than any sort of personal effort.
I’ve never gone through the process of adding in what paper DX QSLs and logs could be added to my LoTW totals. Hard to get interested enough to dedicate the hours to sort this out.
My paper QSLing is way behind, and I am currently in the midst of having my cards redesigned with the updates to my current QTH.
I am intrigued with nearly 50% of my QSOs uploaded to LoTW having been confirmed. Guess that show the system does work.
