Not sure... More satellites in tracking, better positioning because of
lower DOP and measurement redundancy.
You need 4 for 3D fix, but you have no redundancy! No integrity check
and usually not a good DOP.
It is instructive to printout NMEA sentences which show DOPS, Sats used
etc. second by second.... Many "in view satellites" are not used.
