I do not know how you are using your GPS that you question its accuracy.

But if it puts you in the within the area you set out to go to plus or minus 4 meters is that a problem?

You will not be walking off a cliff because your GPS said to walk 4 metes more are you???
I too have been using GPS for over a decade, starting with a Geko. I think you misinterpreted my question: as a hiker and mountaineer, I am generally happy with the accuracy of the horizontal position fix obtained by my 66st which I use for navigation with a variety of installed topo maps for different countries, and haven't walked off any cliffs!

That said, like other OPs on several forums going back over a number of years, I remain curious about what this Garmin accuracy number actually represents.

So to get back to the point of the OP question, unless you are utilizing the Garmin Rinex/Carrier functionality (not for the feint hearted) you won’t be anywhere near approaching sub-metre and the number of metres the device is indicating will most likely be 50% CEP.
@Bushwalker8 That is helpful information, thank you.

I emailed this question to Garmin support some two weeks ago but have yet to receive any response. If I do, I will post it here.
