Dan, or others... Do the Hotchkis shocks 'wear in' some over time and get slightly softer?

I'm still not quite sure if it's just me, getting used to them, or that maybe the adjustable Hotchkis front shocks I'm running since November '14 have gotten slightly softer over time.
I have a feeling the adjusters need to be stepped up again, but I'm already running them at setting 17 or 18 I recall, from the possible max 22? steps.
Last year I started out with the shocks at 15-16 steps up from their shoftest setting.

The Dart still has the 1" JustSuspension torsionbars, but I'm a bit worried I might be running out of adjustment when I install the 1.10" FirmFeel bars in the near future.

(Since the installation I've also swapped the castiron 2bbl intake for a alum. 4bbl intake on the otherwise bone stock 318)
