I carry CO2 simply because that allows me to carry a cheap Bell pump. If it "gets legs", I'm not out much.
Pump the tire up about 20-30 PSI to check bead seating etc. If good, add about 10 more if the pump is still up to it and then hit it with the cartridge. On paper, that should be about right if not a tic low. Plenty good enough to get home on my skinny tires.
I haven't had a flat on that bike to find out how well theory works.
