Still as I noted the speed can varry by 30-40kph due to altitude changes.. Assuming you can hold it pretty steady, more if you cant! So your 50 would/could still be in the noise. The only way to tell is to log the speed and the altidue, than you can 'see' what is going on

That being a pilots's 'perception' of what is going on can be very different from what is 'actually' going on.
