According to tasty brew it is. I am like Yooper I carb everything the same. I currently have my pressure at 10psi. I like it. At 10 PSI (my fridge is also 38F) I get relatively few bubbles coming out of solution. At 12 PSI I get a rain of bubbles. It depends on what you like.
At 4.9PSI you are trusting physics and the charts/calculators. I think it will work but have no experience there. I also have no experience with beers at 1.9 vol of co2. I have had casked ales in England but don't know the volumes of co2.
