Warning: chronographs are inherently deceiving! Unless you know for a fact that the chrono is properly calibrated, you are just ********* in the wind. You can cheat them, too. I work for a company that makes compound bows, and have used chrono's calibrated to Norb Mullaney's graph that is the industry standard, so to speak. Most graphs are not accurate, or even close. You also must have an accurate scale for weighing bow and arrows, or you will not be getting an accurate reading. Also, if you hold at full draw, AT ALL, a guy who is skilled at shooting through a graph will beat your speed every time. The string (and cables on a compound) stretch when you hold, and you lose a few feet, or more. I would bet that the average traditional setup for hunting averages in the low to mid 180's on an accurate graph.
