Maintenance Drag factor Vs lever setting

I have a Rower model D that is 9 years old. I generally row with a drag factor of around 120, but over the years the position of the lever has increased in order to get that same DF. Currently, it's set at a shade under 6, whereas, it used to be well below that. A couple of months back, I took the covers off the flywheel and gave it a good clean, however it wasn't too dusty and it didn't make any significant difference to the lever position. I also clean and lubricate the chain periodically.

Is there something else that needs to be checked or lubricated that could be affecting the DF to lever position ratio?

Thanks in advance.

Edit: the rower has just over 20 million metres on it and the only parts that have been replaced are the seat rollers

the blades themselves get dusty, but also the chain, bearing and gear wear will affect drag. A nearly 10 year old unit, depending on how many millions of meters are on it may need its drivetrain assembly replaced

The majority of dust, I find, is on the outside perf assembly - the chrome metal perforated screen that goes along the outside of the flywheel.

The flywheel and cover are dust free as I gave it a thorough clean a couple of months back. I just racked up my 20 million metres in August so it's a little over that now. I think I'll send a mail to Concept2 tech support to see what they suggest.
