That speed seems about right in my opinion. Based on my similar IBO speed bow, Bowtech RevoltX, 70lb DW, but differing a bit on the mod and DL (I’m at 29.5” with performance mod, and draw stops set to about 80%LO). Also, at the risk of extrapolating beyond my dataset and using a simple linear fit, I would’ve guessed 243 fps or so with your AW 606gr and my bow setup. Again, not apples to apples comparison, but I’d say based on ballpark numbers your 238 fps seems reasonable. My data was measured with the Garmin chronograph.
