show position -only flights/do not showposition only flights

hello ,
what difference if i check show or do not show position-only flights in my account?Could i upload more flights if i check show position or not?
Hope to be clear,thank in advance,kind regards

With “do not show” checked, only flights that file flight plans (typical commercial airliners) will show up in the list of “recent flights with positions from this feeder” and in other places on the site.

With “show” checked, other flights become visible, including those that don’t file flight plans, general aviation, etc.

Your feeder will upload the same data either way, the option simply changes whether or not position-only flights are displayed on the FlightAware website.
