If you suspect the gauge in error, then go get a hand held gauge that will fit your valve stem and check if it shows a big difference from what the pump gauge shows.
I’m pushing down the handle completely, though it doesn’t make a difference in my opinion. I could definitely get a bit more air into the tires, I guess I could maybe even go until 60 PSI. But already at 40 PSI (based on the gauge at least) the tires are quite firm, so I don’t want to risk a blow-off or damage by forcing additional air into the tires.
