The unusable fuel in flight depends very much on the flight conditions. I have done those measurements for the Columbia 400 and found it varies greatly from <1.5 gal (smooth air, wings level) to about 4 gal per tank (wing) in turbulent, sideslip, steep climb or descent conditions. For certified airplanes, the worst case (in this case 4 gal) is declared unusable. Total qty per wing was 50 gal. For the Pulsar, I would think 1/2 gal is appropriate if your pickup is low enough and you do not slosh it around.

Just a word of caution, In a hard long slip the fuel pickup will unport. Flying into Thermal, I usually come in over the mountains at 7500 ft and have to drop to -185 to land at Thermal. So, yes, I do a hard slip to drop altitude at near 1500 ft/min. If I have the tank selected that is away from the slip and I have less than 4 gal. the pickup will unport.
