In fact, I'd generalize to "Acclaim flown by owner on a real trip rather than sales
/demo guy for a magazine." For any real life, safety conscious, actual owner who doesn't want to die because of a simple O2 system malfunction and would prefer not to buy new cylinders every 500 hours, the acclaim is a 210 kt airplane. That 235 figure is at FL250 (very harsh environment on a human) running at some insane ROP power output. Most real use will be in the high teens, LOP at 75-80% power. That will give you 210 KTAS
