it would be better if the psi readout reported tenths of a psi

In presta mode the center push pin used for schraeder mode is spring loaded and must be pushed in while placing over a presta valve. This causes a fair amount of air to expel from the tire you are measuring. So you must over fill the tire first before measuring. Not really a big deal, but you can't just check pressure on a tire without a significant drop in pressure. Also, it would be better if the psi readout reported tenths of a psi.
