Indoor bows are designed to be forgiving. They have a deflex riser, longer axle-to axle easements and a long brace height. All of this adds to a slower set-up. Then you add that large diameter arrows and moderately heavy points that you end up with a bow shooting in the 200-230 fps range. Most indoor shooters are pulling lower poundage, 45-55 seems to be the average, and most prefer a lower let off bow. Target bows are heavy and more holding weight to helps balance the weight of the bow at full draw.
My indoor bow is shooting 198 fps at 54 lbs with a 533 gr arrow.
