I will leave it strung 4 hours at a time like hunting bow,,,,,If I was making a bow for someone, I would want to make sure the tiller does not shift,, so would shoot alot and leave braced a few hours at a time, for several sessions,, if the limbs were reflexed I would be extra patient about shooting the bow in,, or if the bow was pushing the limits in design,, I start shooting the bow when I can draw it to 20 inches hitting target weight,,, before I string the bow the first time, I leave it on the tiller tree at about brace height for a few hours,, "pre sweating" especially a heavy bow,, I find it just a bit easier to string when I do this,, i guess if you shot the bow enough there would be no need
