PTFE Feel of Resistence when inserting filament

Hi everyone. Thanks in advance for your time and help! You forum regulars are incredible!

I have a MK3s with about 800 issue free print hours. Lately I've been getting a lot of partial clogs and under extrusion. 


My question is about what inserting filament should feel like, how much resistence should one feel when inserting it. I m thinking maybe my PTFE tube might be partially clogged with dust or debris. I'm just trying to rule

things out. I've been lurking a lot and have read all the great posts here about heat creep and partial clogging. Happy to start a new topic once I rule this out. Thank you all!
